Description

Technical Field

[0001] The present application relates to the field of mine filling technology, and in particular to a mine filling method, system, device, electronic equipment and storage medium. Background Art

[0002] Mine filling technology plays an increasingly important role in modern mining, especially in dealing with ground subsidence, a problem that plagues the coal industry and the metal mining industry. Mine filling technology is to fill the waste materials generated during mining, such as coal gangue, fly ash, metal mine waste and other solid materials, back into the goaf through filling, so as to achieve "three down" coal mining (i.e. "down mining, down digging, and down filling"). Mine filling technology not only effectively fills the mine voids, but also reduces the risk of ground subsidence. At the same time, mine filling technology can consume the gangue mountains, fly ash, metal mine waste, etc. formed by previous mining, greatly reduce land occupation and reduce environmental damage, so as to effectively protect groundwater resources and land resources, thereby reducing the negative impact of mining on the natural environment. With the increasing demand for mining resources and the continued attention to environmental protection, the application of mine filling technology will become more and more extensive.

[0003] However, in traditional mine filling solutions, the transportation, mixing, pumping and filling processes of solid and liquid materials are usually separated. In this process, solid materials and liquid materials are first mixed in a mixing device to form a certain volume of slurry or paste, which is then pumped to the goaf for filling using a filling pump and pipeline. This filling method requires additional time and resources for each step because the mixing and pumping processes are implemented separately, and continuous mixing and pumping cannot be achieved, resulting in low filling efficiency.

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0022] Embodiments of the present application provide a mine filling method, system, device, electronic device and storage medium.

[0023] The mine filling method can be integrated into an electronic device, which can be a terminal, a server, etc. The terminal can be a mobile phone, a tablet computer, a smart Bluetooth device, a laptop, or a personal computer (PC).

[0025] In some embodiments, the server may also be implemented in the form of a terminal.

[0026] For example, the mine filling method can be applied to Figure 1a The mine filling system shown in the figure includes a liquid material conveying subsystem, a solid material conveying subsystem, a mixing subsystem and a pumping subsystem, and the method includes: obtaining filling fluid parameters corresponding to the goaf to be filled, and a first flow rate of the mine filling system, the first flow rate includes one or two conveying flows of liquid material conveying flow rate, solid material conveying flow rate and filling fluid pump conveying flow rate, and the filling fluid parameters include filling fluid mass concentration and filling fluid density corresponding to the filling fluid mass concentration; based on the filling fluid mass concentration, the filling fluid density and the first flow rate, determining a second flow rate, the second flow rate being liquid The material conveying flow, solid material conveying flow and other conveying flows except the first flow among the filling fluid pump conveying flow; according to the first flow and the second flow, the operating parameters of the liquid material conveying subsystem, the solid material conveying subsystem and the pumping subsystem are set to match the filling fluid mixed flow of the mixing subsystem with the filling fluid pump conveying flow of the pumping subsystem; the goaf to be filled is continuously filled by the liquid material conveying subsystem, the solid material conveying subsystem, the mixing subsystem and the pumping subsystem, and the liquid material conveying subsystem, the solid material conveying subsystem and the pumping subsystem operate based on the set operating parameters.

[0027] It should be noted that the order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0028] In this embodiment, a mine filling method is provided, which is applied to a mine filling system. The mine filling system includes a liquid material conveying subsystem, a solid material conveying subsystem, a mixing subsystem and a pumping subsystem. Figure 1b As shown, the specific process of the mine filling method can be as follows:

[0029] 110. Obtain filling fluid parameters corresponding to the goaf to be filled, and a first flow rate of the mine filling system, the first flow rate including one or two of a liquid material delivery flow rate, a solid material delivery flow rate and a filling fluid pump delivery flow rate, and the filling fluid parameters including a filling fluid mass concentration and a filling fluid density corresponding to the filling fluid mass concentration.

[0030] Wherein, the goaf refers to the hollow area left behind due to the mining of the ore body during the mining process. These areas usually need to be filled to prevent ground collapse or affect the surrounding environment. For example, in an embodiment of the present application, solid materials and liquid materials can be mixed by a mine filling system to form a filling fluid, and then sent to the goaf for filling. The mine filling system includes a liquid material conveying subsystem, a solid material conveying subsystem, a mixing subsystem and a pumping subsystem. Wherein, the liquid material conveying subsystem is used to convey liquid materials such as water or liquid containing chemical additives for filling to the mixing subsystem, the solid material conveying subsystem is used to convey solid materials such as coal gangue, fly ash, metal mine waste, etc. for filling to the mixing subsystem, the mixing subsystem is used to mix the liquid materials conveyed by the liquid material conveying subsystem and the solid materials conveyed by the solid material conveying subsystem to form a filling fluid such as a slurry or paste, and the pumping subsystem is used to pump (i.e., convey) the filling fluid mixed by the mixing subsystem to the goaf for filling.

[0031] Among them, the liquid material delivery flow rate, solid material delivery flow rate and filling fluid pump delivery flow rate are respectively the flow rate of liquid material delivered by the liquid material delivery subsystem, the flow rate of solid material delivered by the solid material delivery subsystem per unit time and the amount of filling fluid pumped (i.e. delivered) by the pumping subsystem. Among them, the liquid material delivery flow rate is the weight of solid material delivered by the solid material delivery subsystem per unit time, the liquid material delivery flow rate is the weight of liquid material delivered by the liquid material delivery subsystem per unit time, and the filling fluid pump delivery flow rate is the volume of slurry pumped out by the pumping subsystem per unit time.

[0032] In the embodiment of the present application, the first flow rate may be a flow rate set according to a filling plan, such as the first flow rate may be set according to an application scenario or actual needs. For example, the corresponding delivery flow rate may be set as the first flow rate for any one of the liquid material delivery subsystem, the solid material delivery subsystem, and the pumping subsystem.

[0033] Among them, the filling fluid refers to the fluid such as slurry or paste used to fill the goaf. The filling fluid is usually a stable state formed by mixing solid materials and liquid materials in a certain proportion without separation. The filling fluid mass concentration and the filling fluid density are the mass concentration of the filling fluid and the density of the filling fluid, respectively. It can be understood that the filling fluid mass concentration is associated with the filling fluid density, and generally increasing the filling fluid mass concentration will generally lead to an increase in its density. For example, in an embodiment of the present application, the filling fluid parameters corresponding to the goaf to be filled, namely the filling fluid mass concentration and the filling fluid density, can be determined based on the current filling operation requirements of the goaf to be filled (such as filling operation conditions).

[0034] Since the physical and chemical properties of the gangue or solid waste produced by the same mine, such as a coal mine or a metal mine, are basically the same. Therefore, the physical and chemical properties of the fluid formed by mixing the solid materials planned to be filled in the same mine with the specific liquid materials are also fixed. Therefore, a small sample mixing test of solid materials and liquid materials can be conducted in advance on the mine corresponding to the goaf to be filled to determine the fluid mass concentration range corresponding to the goaf to be filled, and then determine the filling fluid parameters corresponding to the goaf to be filled based on this. Exemplarily, in some embodiments, obtaining the filling fluid parameters corresponding to the goaf to be filled and the first flow rate of the mine filling system includes: obtaining the fluid mass concentration range corresponding to the goaf to be filled, the fluid mass concentration range is determined by a small sample mixing test of solid materials and liquid materials; based on the filling operation conditions of the goaf to be filled, determining the filling fluid mass concentration from the fluid mass concentration range, and determining the filling fluid density corresponding to the filling fluid mass concentration; obtaining the first flow rate of the mine filling system.

[0035] Among them, the small sample mixing test refers to a mixing test performed using a small-scale sample to evaluate and optimize the mixing process. In the small sample mixing test of the embodiment of the present application, a small batch of solid materials and liquid materials can be used to perform a mixing experiment to determine the range of values ​​of the fluid mass concentration of the filling fluid that can form a stable fluid, that is, the fluid mass concentration range.

[0036] The filling operation conditions refer to the conditions that affect the filling efficiency. In the embodiment of the present application, the filling operation conditions may include but are not limited to one or more of the pumping distance and the filling pipeline resistance, etc. These conditions may affect the flow characteristics of the filling fluid in the filling pipeline, thereby affecting the efficiency of the filling process.

[0037] Therefore, in the embodiment of the present application, a small sample mixing test of solid materials and liquid materials is conducted in advance on the mine corresponding to the goaf to be filled, so as to determine the fluid mass concentration range that can form a stable filling fluid. Then, according to the current filling operation conditions, a fluid mass concentration that meets the filling operation conditions is directly determined from the fluid mass concentration range as the fluid mass concentration corresponding to the goaf to be filled, so as to effectively save the trial and error process of the actual filling operation, improve the filling efficiency and effect, and ensure the stability and reliability of the filling process.

[0038] In practical applications, the fluid mass concentration corresponding to the goaf to be filled can be determined from the fluid mass concentration range based on prior experience or small batch filling tests. For example, in some embodiments, a small batch filling test can be conducted on the goaf to be processed based on the mass concentration of each group of candidate fluids, so as to determine the fluid mass concentration corresponding to the goaf to be filled from the fluid mass concentration range according to the experimental results of the small batch filling test. For example, a small batch of filling fluid corresponding to each group of candidate fluid mass concentrations can be pumped to a filling pipeline through a filling pump, so that the filling fluid is transported to the goaf to be processed by the filling pipeline for filling, and based on the evaluation index of the experimental effect, a group of candidate fluid mass concentrations with the best experimental effect is determined as the fluid mass concentration corresponding to the goaf to be filled. The evaluation index of the experimental effect may include, but is not limited to, one or more of the filling efficiency, the fluidity of the filling fluid in the filling pipeline, and the density of the filling fluid in the goaf to be processed.

[0039] In some embodiments, based on the filling operation conditions of the goaf to be filled, the filling fluid mass concentration is determined from the fluid mass concentration range, and the filling fluid density corresponding to the filling fluid mass concentration is determined, including: selecting multiple candidate filling fluid mass concentrations from the fluid mass concentration range; obtaining multiple groups of candidate filling fluid parameters according to the candidate filling fluid densities measured based on each candidate filling fluid mass concentration, the candidate filling fluid parameters including any candidate filling fluid mass concentration and the corresponding candidate filling fluid density; based on the filling operation conditions of the goaf to be filled, determining the filling fluid parameters corresponding to the goaf to be filled from the multiple groups of candidate filling fluid parameters.

[0040] For example, the mass concentration value range corresponding to the mass concentration of the filling fluid can be determined through a small sample mixing test, and then multiple candidate filling fluid mass concentrations can be selected from the mass concentration value range corresponding to the filling fluid mass concentration, and the filling fluid density corresponding to each candidate filling fluid mass concentration can be measured to determine multiple groups of candidate filling fluid parameters. The multiple groups of candidate filling fluid parameters can be recorded in a table so that the filling fluid parameters corresponding to the goaf to be filled can be selected from the table based on the filling operation conditions of the goaf to be filled. Thus, during the actual filling operation, any group of candidate filling fluid parameters can be selected from multiple groups of known candidate filling fluid parameters, so that they can be quickly adjusted according to the actual filling operation requirements to ensure the smooth progress of the filling operation.

[0041] In the actual filling operation, the above method needs to measure multiple groups of candidate filling fluid parameters in advance, and the filling fluid parameters can only be selected from the several groups of candidate filling fluid parameters measured in advance, and the amount of optional data is small. Considering that different filling fluid mass concentrations have corresponding filling fluid densities. For the same mine, the physical and chemical properties of the fluid formed by mixing the solid materials planned to be filled in the same mine with specific liquid materials are also fixed. Therefore, in the embodiment of the present application, a group of known filling fluid mass concentrations and filling fluid densities are used to derive the filling fluid density corresponding to any filling fluid mass concentration. This method does not require the measurement of multiple groups of filling fluid densities, and is not limited to several known groups of candidate filling fluid parameters. Instead, any filling fluid mass concentration can be selected according to the actual filling operation requirements and the corresponding filling fluid density can be calculated. The amount of data for the optional filling fluid parameters is larger.

[0042] Exemplarily, in some embodiments, based on the filling operation conditions of the goaf to be filled, the filling fluid mass concentration is determined from the fluid mass concentration range, and the filling fluid density corresponding to the filling fluid mass concentration is determined, including: determining a reference filling fluid mass concentration from the fluid mass concentration range; obtaining a reference filling fluid density measured based on the reference filling fluid mass concentration; determining the filling fluid mass concentration corresponding to the goaf to be filled based on the filling operation conditions of the goaf to be filled; and calculating the filling fluid density corresponding to the filling fluid mass concentration based on the reference filling fluid mass concentration, the reference filling fluid density and the filling fluid mass concentration, so as to obtain the filling fluid parameters corresponding to the goaf to be filled.

[0043] For example, a small sample mixing test of solid materials and liquid materials can be conducted in advance on the mine corresponding to the goaf to be filled, so as to determine the mass concentration value range corresponding to the mass concentration of the filling fluid that can form a stable filling fluid. And select a group of filling fluid mass concentrations from the mass concentration value range corresponding to the filling fluid mass concentration as the reference filling fluid mass concentration, and measure the filling fluid density corresponding to the group of reference filling fluid mass concentrations as the reference filling fluid density. Combined with the filling fluid mass concentration corresponding to the current goaf to be filled, the filling fluid density corresponding to the current goaf to be filled is derived. In this way, the filling fluid density corresponding to any filling fluid mass concentration within the mass concentration value range can be directly calculated and determined without measuring the filling fluid density corresponding to the fluid mass concentration in advance, which can reduce the number of times the filling fluid density is measured and improve efficiency.

[0044] For example, in some embodiments, the filling fluid mass C can be calculated by the following formula: m The filling fluid density ρ corresponding to the concentration 浆 :

[0045] ρ 浆 =(ρ0×ρ 液 ×C m0 ) / (ρ0×C m0 -ρ0×C m +ρ 液 ×C m );

[0046] Among them, C m0 is the mass concentration of the reference filling fluid, ρ0 is the density of the reference filling fluid, ρ 液 is the density of liquid material, C m is the mass concentration of the filling fluid corresponding to the goaf to be filled. The density of the liquid material is the density of the liquid material, and the density of the liquid material is ρ 液 is a known parameter, which can be measured by a density measuring tool such as a densitometer, or can be directly determined according to the characteristics of the liquid material. For example, if the liquid material is water, then ρ 液 is the density of water.

[0047] In the above formula, it is known that the mass concentration C of a reference filling fluid measured by a small sample mixing test is m0 and the corresponding reference filling fluid density ρ0, liquid material density ρ 液 , filling fluid mass concentration C m Therefore, the filling fluid mass concentration C can be solved based on these known parameters m is the corresponding filling fluid density ρ 浆 .

[0048] The above formula can be derived through the following process solution process:

[0049] First, based on the reference filling fluid mass concentration C m0 The calculation formula is derived from the reference filling fluid mass concentration C m0 , its corresponding reference filling fluid density ρ0, liquid material density ρ 液 The expression for the ideal density of solid material is expressed as (i.e. the following formula 1).

[0050] Reference filling fluid mass concentration C m0 It can be calculated by the following formula: C m0 =m 固 / m 浆 =m 固 / (ρ0×V 浆 ). Among them, m 固 is the mass of solid material transported per unit time, m 浆 V is the mass of filling fluid delivered per unit time, 浆 It is the volume of filling fluid delivered per unit time.

[0051] Therefore, the solid material transport mass per unit time m 固 It can be expressed as: 固 =ρ0×V 浆 ×C m0 . Liquid material transport mass per unit time m 液 It can be expressed as: 液 =ρ0×V 浆 -m 固 =ρ0×V 浆 ×(1-C m0 ). Liquid material transport volume per unit time: V 液 =ρ0×V 浆 -m 固 .

[0052] The above formula can be substituted into the calculation formula of the ideal density of solid materials for derivation, so that the ideal density of solid materials can be gradually deduced and expressed as: ρ 固 =m 固 / V 固 =(ρ0×V 浆 ×C m0 ) / (V 浆 -V 液 )=(ρ0×V 浆 ×C m0 ) / (V 浆 -m 液 / ρ 液 )=(ρ0×V 浆 ×C m0 ) / (V 浆 -ρ0×V浆 ×(1-C m0 ) / ρ 液 )=(ρ 液 ×ρ0×C m0 ) / (ρ 液 -ρ0+ρ0×C m0 ) (i.e. Formula 1).

[0053] Secondly, based on the filling fluid mass concentration C m The calculation formula is derived from the density ρ of the liquid material 液 , density of solid material ρ 固 , Filling fluid delivery volume per unit time V 浆 , Filling liquid material delivery volume per unit time V 液 The expression of the reference filling fluid mass concentration (i.e. the following formula 2): C m =m 固 / m 浆 =ρ 固 V 浆 / ρ 浆 V 浆 =(ρ 固 (V 浆 -V 液 )) / ρ 浆 V 浆

[0054] =ρ 固 / ρ 浆 -ρ 固 V 液 / ρ 浆 V 浆 (That is, Formula 2).

[0055] Furthermore, the mass m of slurry transported per unit time can be calculated based on 浆 The calculation formula is derived from the filling fluid density ρ 浆 , density of liquid material ρ 液 , density of solid material ρ 固 , Filling liquid material delivery volume per unit time V 液 The volume V of the filling fluid delivered per unit time 浆 The expression of (i.e. the following formula 3).

[0056] The mass m of slurry transported per unit time can be calculated 浆 The calculation formula of m 浆 =m 液 +m 液 =ρ 液 ×V 液 +ρ 固 ×(V 浆 -V 液)=ρ 浆 ×V 浆 , and derive step by step to derive V 液 ×(ρ 液 -ρ 固 )=ρ 浆 ×V 浆 -ρ 固 ×V 浆 , to derive V 液 =V 浆 (ρ 固 -ρ 浆 ) / (ρ 固 -ρ 液 ), to derive V 浆 =V 液 (ρ 固 -ρ 浆 ) / (ρ 固 -ρ 液 ) (i.e. Formula 3).

[0057] Finally, the mass concentration C of the reference filling fluid can be derived by combining Formulas 1 to 3. m0 , refer to the filling fluid density ρ0, liquid material density ρ 液 , the filling fluid mass C corresponding to the goaf to be filled m The concentration of the filling fluid density ρ 浆 expression.

[0058] Among them, we can first substitute formula 3 into formula 2 to obtain the filling fluid density ρ 浆 , density of liquid material ρ 液 , density of solid material ρ 固 The filling fluid mass C m The expression is:

[0059] C m =ρ 固 / ρ 浆 -ρ 固 V 液 / ρ 浆 V 浆

[0060] =ρ 固 / ρ 浆 -(ρ 固 ×(ρ 固 -ρ 浆 )) / (ρ 浆 ×(ρ 固 -ρ 液 ))

[0061] =(ρ 固 ×ρ 浆 -ρ固 ×ρ 液 ) / (ρ 浆 ×ρ 固 -ρ 浆 ×ρ 液 ) (i.e. Formula 4).

[0062] The formula can be substituted into formula 4 to obtain the reference filling fluid mass concentration C m0 , refer to the filling fluid density ρ0, liquid material density ρ 液 , concentration filling fluid density ρ 浆 The filling fluid mass C m The expression of: C m =(ρ0×C m0 ×(ρ 浆 -ρ 液 )) / (ρ 浆 ×(ρ0-ρ 液 )), the density of the filling fluid can be obtained by transforming the expression 浆 The expression is:

[0063] ρ 浆 =(ρ0×ρ 液 ×C m0 ) / (ρ0×C m0 -ρ0×C m +ρ 液 ×C m ).

[0064] 120. Determine a second flow rate based on the filling fluid mass concentration, the filling fluid density and the first flow rate, where the second flow rate is the liquid material delivery flow rate, the solid material delivery flow rate and other delivery flows of the filling fluid pump except the first flow rate.

[0065] Since in the mine filling system, the filling fluid is obtained by mixing liquid materials and solid materials. In order to enable the mine filling system to achieve automated filling of continuous conveying, continuous mixing and continuous pumping, it is necessary to maintain a certain relationship between the liquid material conveying flow rate, the solid material conveying flow rate and the filling fluid pump conveying flow rate. Therefore, in the embodiment of the present application, another flow rate that meets the continuous mixing and pumping requirements can be derived based on one or more known conveying flows among the liquid material conveying flow rate, the solid material conveying flow rate and the filling fluid pump conveying flow rate. In this derivation process, the filling fluid mass concentration and filling fluid density required by the current filling operation can be added so that the derived flow rate meets the current filling operation requirements.

[0066] In some embodiments, the first flow rate includes two of a liquid material delivery flow rate, a solid material delivery flow rate, and a filling fluid pumping delivery flow rate, that is, the second flow rate to be determined includes one delivery flow rate.

[0067] In some embodiments, the first flow rate includes one of a liquid material conveying flow rate, a solid material conveying flow rate, and a filling fluid pumping conveying flow rate, that is, the second flow rate to be determined includes two conveying flows.

[0068] For example, in some embodiments, the second flow rate can be calculated based on the calculation relationship associated with the filling fluid mass concentration, the filling fluid density, the liquid material delivery flow rate, the solid material delivery flow rate, and the filling fluid pump delivery flow rate, so as to more accurately calculate the required flow value and improve the accuracy of the system. Specifically, based on the filling fluid mass concentration, the filling fluid density, and the first flow rate, determining the second flow rate includes: obtaining the calculation relationship between the filling fluid mass concentration, the filling fluid density, the liquid material delivery flow rate, the solid material delivery flow rate, and the filling fluid pump delivery flow rate; based on the filling fluid mass concentration, the filling fluid density, and the first flow rate, solving the calculation relationship to obtain the second flow rate.

[0069] In some embodiments, the calculation relationship includes at least one of a first relationship, a second relationship, a third relationship and a fourth relationship, the first relationship is used to express the calculation relationship between the filling fluid mass concentration, the solid material delivery flow rate and the liquid material delivery flow rate, the second relationship is used to express the calculation relationship between the solid material delivery flow rate, the filling fluid pump delivery flow rate, the filling fluid mass concentration, and the filling fluid mass concentration, the third relationship is used to express the calculation relationship between the liquid material delivery flow rate, the filling fluid pump delivery flow rate, the filling fluid mass concentration, and the solid material delivery flow rate, and the fourth relationship is used to express the calculation relationship between the filling fluid pump delivery flow rate, the filling fluid mass concentration, the solid material delivery flow rate and the filling fluid mass concentration.

[0070] For example, the filling fluid mass concentration C m It can be calculated by the solid material delivery flow rate m, liquid material delivery flow rate Q, liquid material density ρ 液 It is calculated by the following formula: C m =m / (Q×ρ 液 +m)×100%, which is the first relation. Among them, the liquid material density ρ 液 are known parameters.

[0071] The solid material delivery flow rate m can be replaced by the filling fluid pump delivery flow rate Q 浆 , filling fluid density ρ 浆 , filling fluid mass concentration C m Calculated by the following formula: m = Q浆 ×ρ 浆 ×C m , which is the second relation.

[0072] Liquid material delivery flow rate Q can be delivered by the filling fluid pump flow rate Q 浆 , filling fluid mass concentration ρ 浆 , solid material conveying flow rate m, liquid material density ρ 液 It is calculated by the following formula: Q = (Q 浆 ×ρ 浆 -m) / ρ 液 , which is the third relation.

[0073] Filling fluid pump delivery flow Q 浆 It can be determined by the filling fluid density ρ 浆 , filling fluid mass concentration C m , the solid material conveying flow rate m is calculated by the following formula: Q 浆 =m / (C m ×ρ 浆 ), which is the fourth relation.

[0074] The known filling fluid mass concentration C m , filling fluid density ρ 浆 , the first flow rate is substituted into one or more of the first to fourth relationship equations to obtain the second flow rate.

[0075] For example, when the first flow rate includes one of a liquid material delivery flow rate, a solid material delivery flow rate, and a filling fluid pumping delivery flow rate, when the filling fluid mass concentration C m , filling fluid density ρ 浆 , liquid material density ρ 液 Under the premise that is known, the second flow rate can be calculated by at least two of the first to fourth relationship equations:

[0076] When the first flow rate includes the liquid material delivery flow rate Q, it means that the liquid material delivery flow rate Q is known. The filling fluid mass concentration C m , liquid material delivery flow rate Q, liquid material density ρ 液 Substitute into the first relation and solve to get the solid material delivery flow rate m. The filling fluid mass concentration C m , solid material conveying flow rate m, filling fluid density ρ 浆 Substitute into the fourth relationship and solve to obtain the filling fluid pump delivery flow rate Q 浆 .

[0077] When the first flow rate includes the solid material delivery flow rate m, it means that the solid material delivery flow rate m is known. The filling fluid mass concentration Cm , solid material conveying flow rate m, liquid material density ρ 液 Substitute into the first relation and solve to get the liquid material delivery flow rate Q. The filling fluid mass concentration C m , solid material conveying flow rate m, filling fluid density ρ 浆 Substitute into the fourth relationship and solve to obtain the filling fluid pump delivery flow rate Q 浆 .

[0078] When the first flow rate includes the filling fluid pump delivery flow rate Q 浆 When the filling fluid pump delivers the flow rate Q 浆 It is known that the filling fluid mass concentration C m , filling fluid density ρ 浆 , Filling fluid pump delivery flow Q 浆 Substitute into the second relation and solve to get the solid material delivery flow rate m. The filling fluid pump delivery flow rate Q 浆 , filling fluid mass concentration ρ 浆 , solid material conveying flow rate m, liquid material density ρ 液 Substitute into the third relationship and solve to obtain the liquid material delivery flow rate Q.

[0079] For example, when the first flow rate includes two of the liquid material delivery flow rate, the solid material delivery flow rate and the filling fluid pumping delivery flow rate, when the filling fluid mass concentration C m , filling fluid density ρ 浆 , liquid material density ρ 液 Under the premise that is known, the second flow rate can be calculated by at least one of the first to fourth relationship equations:

[0080] When the first flow rate includes the liquid material delivery flow rate Q and the solid material delivery flow rate m, it means that the liquid material delivery flow rate Q and the solid material delivery flow rate m are known. The liquid material delivery flow rate Q, the solid material delivery flow rate m, and the filling fluid mass concentration C m , solid material conveying flow rate m, filling fluid density ρ 浆 Substitute multiple of them into the second relational expression, the third relational expression, or the fourth relational expression to obtain the filling fluid pump delivery flow rate Q 浆 .

[0081] When the first flow rate includes the filling fluid pump delivery flow rate Q 浆 When the solid material delivery flow rate m is equal to the filling fluid pump delivery flow rate Q 浆 The solid material delivery rate m is known. The filling fluid pump delivery rate Q 浆 , filling fluid mass concentration ρ 浆 , solid material conveying flow rate m, liquid material density ρ液 Substitute into the first relational expression or the third relational expression and solve to obtain the liquid material delivery flow rate Q.

[0082] When the first flow rate includes the liquid material delivery flow rate Q and the fluid pump delivery flow rate Q 浆 When the liquid material delivery flow rate Q and the fluid pump delivery flow rate Q are 浆 , filling fluid density ρ 浆 Substitute into the first relational expression, the second relational expression, or the third relational expression to obtain the solid material conveying flow rate m.

[0083] 130. According to the first flow rate and the second flow rate, set the operating parameters of the liquid material conveying subsystem, the solid material conveying subsystem and the pumping subsystem so that the filling fluid mixing flow rate of the mixing subsystem matches the filling fluid pump conveying flow rate of the pumping subsystem.

[0084] The operating parameters of the liquid material conveying subsystem, the solid material conveying subsystem and the pumping subsystem can be parameters that can affect the actual conveying flow of the liquid material conveying subsystem, the solid material conveying subsystem and the pumping subsystem in the filling operation. The filling fluid mixed flow refers to the mixing amount of the mixing subsystem per unit time.

[0085] It should be noted that the serial numbers 110, 120, 130, and 140 of the embodiments of the present application do not limit the execution order of the steps. Therefore, the order of setting the operating parameters of the liquid material conveying subsystem, the solid material conveying subsystem, and the pumping subsystem can be adjusted according to the application scenario or actual needs, and the embodiments of the present application do not limit it. For example, after determining any flow rate of the first flow rate and the second flow rate, the operating parameters of the corresponding system can be set according to the flow rate immediately, or after determining all the first flow rates and the second flow rates, the operating parameters of the corresponding system can be set together.

[0086] Exemplarily, in some embodiments, the operating parameters of the liquid material conveying subsystem, the solid material conveying subsystem and the pumping subsystem are set according to the first flow rate and the second flow rate so that the filling fluid mixed flow rate of the mixing subsystem matches the filling fluid pump conveying flow rate of the pumping subsystem, including: setting the operating parameters of the liquid material conveying subsystem according to the liquid material conveying flow rate in the first flow rate and the second flow rate so that the actual conveying flow rate of the liquid material matches the liquid material conveying flow rate; setting the operating parameters of the solid material conveying subsystem according to the solid material conveying flow rate in the first flow rate and the second flow rate so that the actual conveying flow rate of the solid material matches the solid material conveying flow rate; setting the operating parameters of the pumping subsystem according to the filling fluid pump conveying flow rate in the first flow rate and the second flow rate so that the actual pumping flow rate of the pumping subsystem matches the filling fluid mixed flow rate of the mixing subsystem, and the filling fluid mixed flow rate corresponds to the filling fluid pump conveying flow rate.

[0087] For example, in an embodiment of the present application, the operating parameters of the liquid material conveying subsystem, the solid material conveying subsystem and the pumping subsystem can be set respectively so that the actual conveying flow rates of the liquid material conveying subsystem, the solid material conveying subsystem and the pumping subsystem are consistent with the liquid material conveying flow rate, the solid material conveying flow rate and the filling fluid pump conveying flow rate in the first flow rate and the second flow rate.

[0088] It can be understood that, since in the mine filling system, the mixing subsystem connects the liquid material conveying system, the solid material conveying subsystem and the pumping subsystem to obtain the filling fluid by mixing the liquid material and the solid material, and then the pumping subsystem pumps the mixed filling fluid to the goaf for filling, the filling fluid mixed flow of the mixing subsystem is affected by the liquid material conveying flow and the solid material conveying flow, and the filling fluid mixed flow will also affect the filling fluid pump delivery flow. In the embodiment of the present application, by setting the operating parameters of the liquid material conveying subsystem and the solid material conveying subsystem, the actual filling fluid mixed flow when the mixing subsystem is operating is matched with the filling fluid pump delivery flow (such as equal), and by setting the operating parameters of the pumping subsystem, the actual filling fluid pump delivery flow when the pumping subsystem is operating is also matched with the filling fluid pump delivery flow (such as equal), so that the actual filling fluid mixed flow when the mixing subsystem is operating is matched with the actual filling fluid pump delivery flow when the pumping subsystem is operating (such as equal).

[0089] In some embodiments, the liquid material delivery subsystem includes a flow meter that can measure the flow rate of the delivered liquid material (i.e., the actual liquid material delivery flow rate) in real time. The mine filling method also includes: comparing the actual liquid material delivery flow rate with the liquid material delivery flow rate in the first flow rate and the second flow rate, and adjusting the operating parameters of the liquid material delivery subsystem according to the comparison result. In this way, the actual liquid material delivery flow rate is made the same as the liquid material delivery flow rate.

[0090] In some embodiments, the solid material conveying subsystem includes a material weighing device, which can measure the conveying weight of the solid material per unit time in real time, that is, the actual solid material conveying flow rate. The mine filling method also includes: comparing the actual solid material conveying flow rate with the solid material conveying flow rates in the first flow rate and the second flow rate, and adjusting the operating parameters of the solid material conveying subsystem according to the comparison result. In this way, the actual solid material conveying flow rate is the same as the solid material conveying flow rate.

[0091] In some embodiments, the operating parameters of the liquid material conveying subsystem may include the liquid material conveying rate of the liquid material conveying subsystem, such as the feed rate and the discharge rate, and the specific setting method may be set according to the actual application scenario and requirements. By setting the liquid material conveying rate, the actual conveying flow rate of the liquid material is matched with the liquid material conveying flow rate.

[0092] In some embodiments, the operating parameters of the solid material conveying subsystem may include the liquid material conveying rate of the solid material conveying subsystem, such as the feed rate and the discharge rate, and the specific setting method may be set according to the actual application scenario and requirements. By setting the solid material conveying rate, the actual conveying flow rate of the solid material is matched with the solid material conveying flow rate.

[0093] In some embodiments, the operating parameters of the pumping subsystem may include operating parameters of a filling pump such as a booster pump, and the specific setting method may be set according to actual application scenarios and requirements, so that the actual pumping flow of the pumping subsystem matches the filling fluid mixing flow of the mixing subsystem.

[0094] In some embodiments, the filling fluid mixing flow rate can be the same as the filling fluid pump delivery flow rate. The operating parameters of the mixing subsystem, such as the feed rate and the discharge rate, can be set. For example, the operating parameters of the discharge pump in the mixing subsystem can be set to make the filling fluid mixing flow rate the same as the filling fluid pump delivery flow rate, so that the filling fluid obtained by real-time mixing of the mixing subsystem can be pumped in real time to achieve continuous mixing and pumping.

[0095] 140. The goaf to be filled is continuously filled by means of a liquid material conveying subsystem, a solid material conveying subsystem, a mixing subsystem and a pumping subsystem. The liquid material conveying subsystem, the solid material conveying subsystem and the pumping subsystem operate based on set operating parameters.

[0096] For example, in an embodiment of the present application, based on the set operating parameters, it is possible to ensure that the flow rates during the conveying, mixing and pumping processes of the mine filling system are matched, so that the relationship between the actual flow rates during operation of the liquid material conveying subsystem, the solid material conveying subsystem and the pumping subsystem meets the automated filling requirements of continuous conveying, continuous mixing and continuous pumping, so as to realize automated filling of continuous conveying, continuous mixing and continuous pumping and improve the efficiency of the filling operation.

[0097] In addition, since the filling fluid mass concentration and filling fluid density required by the current filling operation are added in the process of determining the second flow rate, the filling fluid actually pumped during operation of the pumping subsystem also meets the filling fluid mass concentration and filling fluid density of the filling fluid required by the current filling operation of the goaf to be filled.

[0098] In some embodiments, the mixing subsystem includes a filling fluid measuring device for measuring actual filling fluid parameters. The filling fluid measuring device refers to a device for measuring the actual filling fluid mass concentration (i.e., actual filling fluid mass concentration) and / or the actual filling fluid density (i.e., actual filling fluid density) of the filling fluid mixed by the mixing subsystem. For example, the filling fluid measuring device can be one or more of a densitometer, a concentration meter, and a concentration meter. For example, the mixing subsystem includes a circulation pipeline, and a densitometer and / or a concentration meter and / or a concentration meter are installed on the circulation pipeline to measure the density value and / or concentration value of the mixed filling fluid in real time.

[0099] For example, in some embodiments, the actual measured filling fluid parameters can be compared with the filling fluid mass concentration and / or filling fluid density to ensure that the filling fluid parameters of the filling fluid actually filled are as consistent as possible with the set ones, and to ensure that the filling operation effect meets the requirements. Specifically, the actual filling fluid parameters include at least one of the actual filling fluid mass concentration and the actual filling fluid density. The mine filling method also includes: obtaining the actual filling fluid parameters measured by the filling fluid measuring device; comparing the actual filling fluid parameters with the filling fluid mass concentration and / or filling fluid density to obtain a comparison result; according to the comparison result, adjusting the set operating parameters of the liquid material conveying subsystem, the solid material conveying subsystem and the pumping subsystem to obtain the adjusted operating parameters, and the liquid material conveying subsystem, the solid material conveying subsystem and the pumping subsystem operate based on the adjusted operating parameters.

[0100] For example, Figure 1c The schematic diagram of the mine filling method applied to the mine filling system shown in the figure can be used to install a filling fluid measuring device such as a densitometer or a concentration meter or a density meter in the mixing subsystem to measure the density value (i.e., the actual filling fluid density) and / or concentration value (i.e., the actual filling fluid mass concentration) of the mixed filling fluid in real time. The measured density value or concentration value is compared with the filling fluid mass concentration and the corresponding filling fluid density of the goaf to be filled (such as calculating the difference), and the operating parameters of the material conveying system and the pumping subsystem are automatically adjusted according to the compared difference to ensure that the density value or concentration value of the filling fluid actually filled is as consistent as possible with the set value, and to ensure that the filling operation effect meets the requirements.

[0101] In some embodiments, the mine filling system further includes a filling subsystem, which is used to fill the goaf to be filled with the filling fluid pumped by the pumping subsystem. For example, the pumping subsystem can pump the filling fluid to the filling pipeline in the filling system through the filling pump, so that the filling fluid is transported to the goaf through the filling pipeline. The filling pump can be a pressure pump.

[0102] In some embodiments, the mine filling system also includes a control subsystem, which is used to execute steps 110 to 130, that is, the filling fluid parameters corresponding to the goaf to be filled and the first flow rate of the mine filling system can be input into the control subsystem as set parameters. The control subsystem can calculate and set the operating parameters of the liquid material conveying subsystem, the solid material conveying subsystem and the pumping subsystem according to the input parameters to ensure that the density value or concentration value of the filling fluid actually filled is as consistent as possible with the set value, so as to ensure that the filling operation effect meets the requirements.

[0103] For example, it can be achieved by Figure 1d The mine filling method shown realizes automated filling of continuous conveying, continuous mixing and continuous pumping. Specifically, the mine filling method may include the following steps A1 to A4:

[0104] Step A1, determine the filling fluid parameters corresponding to the goaf to be filled. In this step, the filling fluid parameters can be determined based on the filling operation conditions of the goaf to be filled, from multiple groups of candidate filling fluid parameters determined by small sample mixing tests of solid materials and liquid materials. It can also be calculated by the control subsystem based on the filling operation conditions of the goaf to be filled, from the reference filling fluid mass concentration, the reference filling fluid density and the liquid material density. In this way, the small sample mixing test only needs to test the reference filling fluid density corresponding to a certain reference filling fluid mass concentration, thereby reducing the workload, and before the filling operation, the filling fluid mass concentration can be arbitrarily selected according to the needs, without measuring the corresponding filling fluid density in advance, which has greater selectivity.

[0105] Step A2: input the determined filling fluid parameters into the control subsystem as basic parameters.

[0106] Step A3: Input the planned first filling flow into the control subsystem, and set the corresponding subsystem operation parameters according to the first flow. The first flow includes the liquid material delivery flow Q (m 3 / h), solid material delivery flow rate m (t / h) and filling fluid pump delivery flow rate Q 浆 (m 3 / h) or both of the delivery flow rate, liquid material density ρ 液 is a known parameter. The first subsystem includes one or two of a liquid material conveying subsystem, a solid material conveying subsystem and a pumping subsystem.

[0107] When the first flow rate includes liquid material conveying flow rate and / or solid material conveying flow rate, the liquid material conveying subsystem or the solid material conveying subsystem can measure the actual liquid material conveying flow rate and / or the actual solid material conveying flow rate in real time through a flow meter and / or a material weighing device, so that the control subsystem can compare them with the input first flow rate. The control subsystem automatically adjusts the operating parameters of the liquid material conveying subsystem and / or the solid material conveying subsystem according to the comparison result to ensure that the real-time measurement of the actual liquid material conveying flow rate and / or the actual solid material conveying flow rate is the same as the input first flow rate.

[0108] Step A4, the control subsystem calculates the second flow rate according to the input filling fluid parameters and the first flow rate, and sets the corresponding subsystem operating parameters according to the calculated second flow rate. The second flow rate is the liquid material delivery flow rate, the solid material delivery flow rate and the filling fluid pump delivery flow rate other than the first flow rate. The second subsystem and the third subsystem include the liquid material delivery subsystem, the solid material delivery subsystem and the pumping subsystem except the first subsystem.

[0109] When the second flow rate includes liquid material conveying flow rate and / or solid material conveying flow rate, when the second flow rate is calculated, the liquid material conveying subsystem and / or the solid material conveying subsystem can measure the actual liquid material conveying flow rate and / or the actual solid material conveying flow rate in real time through a flow meter and / or a material weighing device, so that the control subsystem can compare them with the calculated second flow rate, and the control subsystem automatically adjusts the operating parameters of the liquid material conveying subsystem and / or the solid material conveying subsystem according to the comparison result to ensure that the real-time measurement of the actual liquid material conveying flow rate and / or the actual solid material conveying flow rate is the same as the calculated second flow rate.

[0110] The mine filling method may also include the steps of: the control subsystem adjusts the set operating parameters of the liquid material conveying subsystem, the solid material conveying subsystem and the pumping subsystem according to the comparison results of the actual filling fluid parameters measured by the mixing subsystem and the filling fluid mass concentration and / or filling fluid density.

[0111] The control system compares the density value or concentration value measured by the density meter or concentration meter or concentration meter of the mixing subsystem with the filling fluid mass concentration and / or filling fluid density input into the control subsystem. The control subsystem automatically adjusts the operating parameters of the solid material conveying system and the pumping system according to the comparison difference to adjust the conveying flow rate m (t / h) of the solid material and the flow rate value Q of the filling fluid to be pumped. 浆 (m 3 / h), to ensure that the actual filling fluid mass concentration and / or the actual filling fluid density of the filling fluid actually filled are as consistent as possible with the settings, and to ensure that the filling operation effect meets the requirements.

[0112] The mine filling solution provided in the embodiments of the present application can be applied in various mine filling scenarios. For example, taking a coal mine or a metal mine as an example, the filling fluid parameters corresponding to the goaf to be filled and the first flow rate of the mine filling system are obtained, the first flow rate includes one or two of the liquid material conveying flow rate, the solid material conveying flow rate and the filling fluid pump conveying flow rate, and the filling fluid parameters include the filling fluid mass concentration and the filling fluid density corresponding to the filling fluid mass concentration; based on the filling fluid mass concentration, the filling fluid density and the first flow rate, the second flow rate is determined, and the second flow rate is the liquid material conveying flow rate, the solid material conveying flow rate and the filling fluid pump conveying flow rate except the first flow rate; according to the first flow rate and the second flow rate, the operating parameters of the liquid material conveying subsystem, the solid material conveying subsystem and the pumping subsystem are set to match the filling fluid mixed flow rate of the mixing subsystem with the filling fluid pump conveying flow rate of the pumping subsystem; the goaf to be filled is continuously filled by the liquid material conveying subsystem, the solid material conveying subsystem, the mixing subsystem and the pumping subsystem, and the liquid material conveying subsystem, the solid material conveying subsystem and the pumping subsystem operate based on the set operating parameters.

[0113] As can be seen from the above, the embodiment of the present application can derive two additional flow rates that meet the continuous mixing and pumping requirements based on any one of the liquid material delivery flow rate, the solid material delivery flow rate, and the filling fluid pump delivery flow rate. In the derivation process, the filling fluid mass concentration and the filling fluid density required by the current filling operation can be added so that the derived flow rate meets the current filling operation requirements. At the same time, the operating parameters of the liquid material delivery subsystem, the solid material delivery subsystem, and the pumping subsystem are set by the liquid material delivery flow rate, the solid material delivery flow rate, and the filling fluid pump delivery flow rate, so that the actual delivery flow rate of the liquid material delivery subsystem, the solid material delivery subsystem, and the pumping subsystem is consistent with the liquid material delivery flow rate, the solid material delivery flow rate, and the filling fluid pump delivery flow rate in the first flow rate and the second flow rate. In this way, the flow rates during the conveying, mixing and pumping processes of the mine filling system are matched, so that the relationship between the actual flow rates during the operation of the liquid material conveying subsystem, the solid material conveying subsystem and the pumping subsystem meets the automated filling requirements of continuous conveying, continuous mixing and continuous pumping, so as to realize automated filling of continuous conveying, continuous mixing and continuous pumping, thereby improving the efficiency of the filling operation.

[0114] In order to better implement the above method, the present application embodiment also provides a mine filling system, such as Figure 2aThe structure diagram of the mine filling system shown in the figure includes a liquid material conveying subsystem 210, a solid material conveying subsystem 220, a mixing subsystem 230 and a pumping subsystem 240. The mine filling system is used to implement the steps in any mine filling method provided in the embodiments of the present application. For example, the mine filling system can be used to implement the following steps:

[0115] Obtain filling fluid parameters corresponding to the goaf to be filled, and a first flow rate of the mine filling system, the first flow rate including one or two of the liquid material conveying flow rate, the solid material conveying flow rate and the filling fluid pump conveying flow rate, and the filling fluid parameters including the filling fluid mass concentration and the filling fluid density corresponding to the filling fluid mass concentration; determine a second flow rate based on the filling fluid mass concentration, the filling fluid density and the first flow rate, the second flow rate being the liquid material conveying flow rate, the solid material conveying flow rate and the filling fluid pump conveying flow rate other than the first flow rate; set operating parameters of the liquid material conveying subsystem, the solid material conveying subsystem and the pumping subsystem according to the first flow rate and the second flow rate, so that the filling fluid mixed flow rate of the mixing subsystem matches the filling fluid pump conveying flow rate of the pumping subsystem; continuously fill the goaf to be filled through the liquid material conveying subsystem, the solid material conveying subsystem, the mixing subsystem and the pumping subsystem, and the liquid material conveying subsystem, the solid material conveying subsystem and the pumping subsystem operate based on the set operating parameters.

[0116] In some embodiments, the mine filling system also includes a control subsystem, which is used to obtain filling fluid parameters corresponding to the goaf to be filled, and a first flow rate of the mine filling system, the first flow rate includes one or two of the liquid material conveying flow rate, the solid material conveying flow rate and the filling fluid pump conveying flow rate, and the filling fluid parameters include the filling fluid mass concentration and the filling fluid density corresponding to the filling fluid mass concentration; based on the filling fluid mass concentration, the filling fluid density and the first flow rate, the second flow rate is determined, and the second flow rate is the liquid material conveying flow rate, the solid material conveying flow rate and the filling fluid pump conveying flow rate except the first flow rate; according to the first flow rate and the second flow rate, the operating parameters of the liquid material conveying subsystem, the solid material conveying subsystem and the pumping subsystem are set to make the filling fluid mixed flow of the mixing subsystem match the filling fluid pump conveying flow of the pumping subsystem.

[0117] In some embodiments, the mine filling system further comprises a filling subsystem, which is used to fill the goaf to be filled with a filling fluid pumped by the pumping subsystem. Figure 2b The structural schematic diagram of the mine filling system shown in the figure includes a control subsystem, a liquid material conveying subsystem, a solid material conveying subsystem, a mixing subsystem, a pumping subsystem and a filling subsystem.

[0118] As can be seen from the above, the mine filling system provided in this embodiment can derive two additional flow rates that meet the continuous mixing and pumping requirements based on any one of the liquid material delivery flow rate, the solid material delivery flow rate, and the filling fluid pump delivery flow rate through the control subsystem. In this derivation process, the filling fluid mass concentration and the filling fluid density required by the current filling operation can be added so that the derived flow rate meets the current filling operation requirements. At the same time, the control subsystem sets the operating parameters of the liquid material delivery subsystem, the solid material delivery subsystem, and the pumping subsystem through the liquid material delivery flow rate, the solid material delivery flow rate, and the filling fluid pump delivery flow rate, so that the actual delivery flow rates of the liquid material delivery subsystem, the solid material delivery subsystem, and the pumping subsystem are consistent with the liquid material delivery flow rate, the solid material delivery flow rate, and the filling fluid pump delivery flow rate in the first flow rate and the second flow rate. In this way, the flow rates during the conveying, mixing and pumping processes of the mine filling system are matched, so that the relationship between the actual flow rates during the operation of the liquid material conveying subsystem, the solid material conveying subsystem and the pumping subsystem meets the automated filling requirements of continuous conveying, continuous mixing and continuous pumping, so as to realize automated filling of continuous conveying, continuous mixing and continuous pumping, thereby improving the efficiency of the filling operation.

[0119] In order to better implement the above method, the present application also provides a mine filling device.

In the derivation process, the filling fluid mass concentration and the filling fluid density required by the current filling operation can be added so that the derived flow rate meets the current filling operation requirements.
