Description

Technical Field

[0001] The present invention relates to the technical field of mining, and particularly relates to a device for measuring the acting range of backfill granular materials on an inclined sidewall and a using method thereof. Background Art

[0002] Currently, with the development of the mining industry and the improvement of environmental protection requirements, more and more mining enterprises fill materials such as waste rock and tailings into the stope to maintain the stability of surrounding rocks and avoid surface subsidence. The mechanical properties of backfill granular materials are between those of water and solids, and their mechanical interaction with surrounding rocks is very complex. Scholars at home and abroad have carried out a large number of theoretical studies on the lateral pressure and vertical pressure of backfill granular materials.

[0003] At present stage, the main calculation formulas for the vertical pressure of backfill granular materials are obtained by taking the micro-elements in a two-dimensional stope with parallel sidewalls as the research object and establishing limit equilibrium equations. The derivation process is based on the assumption that the lateral pressure coefficient of backfill granular materials is a fixed value. However, in steeply inclined stopes, the action of backfill granular materials on the sidewall and floor rock masses is very complex. Only on the basis of accurately obtaining the mechanical action range of backfill granular materials and inclined sidewall rock masses in the stope can the interaction mechanism between surrounding rocks and backfill granular materials be further revealed, the accurate lateral pressure coefficient of backfill granular materials be obtained, and then an accurate theoretical formula for the force of backfill granular materials on rock masses be established. This theoretical formula is an important basis for evaluating the filling effect of backfill granular materials and the filling design of backfill granular materials.

[0004] Therefore, there is an urgent need for a device for measuring the acting range of backfill granular materials on an inclined sidewall and a using method thereof with a wide application range and high accuracy. Summary of the Invention

[0039] To better understand the above technical solutions, the exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art. Among them, the orientation nouns such as "upper", "lower", "left", and "right" mentioned herein are based on Figure 1 the orientation as a reference.

[0040] Embodiment 1:

[0041] As Figures 1-4As shown in the figure, this embodiment provides a device for measuring the action range of filled bulk solids on an inclined sidewall, including a main frame, a filled bulk solid measurement assembly, an elastic member, and a force application mechanism 2. The filled bulk solid measurement assembly is installed in the measurement area inside the main frame. The filled bulk solid measurement assembly includes two sidewall plates on the left and right, two connecting members on the left and right, two baffles, and a bottom plate. The bottom ends of the two sidewall plates are rotatably connected to the bottom of the measurement area. The bottom plate is located between the bottom ends of the two sidewall plates. The two baffles are installed on the front and rear sides of the measurement area to form a filled bulk solid loading space with an upward opening. Among them, the inner sides of the two front and rear baffles 33 are in contact with the front and rear sides of the bottom ends of the two sidewall plates. The bottom end of the baffle 33 is in contact with the top of the bottom plate 34. The top ends of the two sidewall plates are respectively connected to the bottom of the main frame through an elastic member. The two connecting members are respectively connected between the force application mechanism 2 and the two sidewall plates, and the force application mechanism 2 and the two connecting members can be selectively connected between a engaged state and a disengaged state. When the force application mechanism 2 and the two connecting members are in the engaged state, the elastic member is in a stretched state, and the two sidewall plates respectively have a certain inclination angle. When the force application mechanism 2 and the two connecting members synchronously enter the disengaged state from the engaged state, the elastic member drives the two sidewall plates to rotate in opposite directions. Among them, the force application mechanism 2 is a telescopic mechanism. The inner sides of the two sidewall plates are selectively connected to the power output end 21 of the telescopic mechanism, and the outer sides of the two sidewall plates are connected to the elastic member.

[0042] Specifically, through the filled bulk solid loading space formed by the filled bulk solid measurement assembly, the working conditions of the stope can be simulated. Different heights and different particle parameter filled bulk solids can be filled into the filled bulk solid loading space, which can simulate the filling conditions of filled bulk solids with different parameters in the stope, and the measurement range is wide. Then, by instantaneously releasing the restrictions on the left and right sides of the filled bulk solid loading space through the force application mechanism 2 and the elastic member, part of the filled bulk solid will fall along both sides of the filled bulk solid loading space. By the weight of the filled bulk solid scattered outside the filled bulk solid loading space and the natural angle of repose (the maximum angle at which the filled bulk solid can maintain a natural stable state when stacked) formed by the remaining filled bulk solid in the filled bulk solid loading space, the action range of the filled bulk solid on the inclined sidewall can be obtained. Compared with the prior art, it can accurately obtain the action range of filled bulk solids with different particle parameters at different filling heights of the filled bulk solid on the inclined sidewall according to the working conditions of the stope, further obtain the corresponding filled bulk solid lateral pressure coefficient, and then be able to establish an accurate theoretical formula for the force of the filled bulk solid on the rock mass, filling the theoretical defects in evaluating the filling effect of the filled bulk solid and the filling design of the filled bulk solid, which is of great significance for preventing surface subsidence.

[0043] Specifically, as Figures 1-5As shown, the two side wall panels are the left side wall panel 31 and the right side wall panel 32 respectively, and the two connecting members are the left connecting member 35 and the right connecting member 36 respectively. The bottom ends of the left side wall panel 31 and the right side wall panel 32 are rotatably installed at the bottom of the measurement area. By the rotatable left side wall panel 31 and right side wall panel 32, the dips of different hanging wall surrounding rocks and footwall surrounding rocks can be simulated. The left side of the left side wall panel 31 and the right side of the right side wall panel 32 are respectively connected to the bottom of the main frame 1 through elastic members. The upper right part of the left side wall panel 31 is selectively connected to the power output end 21 of the telescopic mechanism through the left connecting member 35. The upper left part of the right side wall panel 32 is selectively connected to the power output end 21 of the telescopic mechanism through the right connecting member 36. Thus, on the one hand, the left side wall panel 31 and the right side wall panel 32 can be respectively connected to the power output end 21 of the telescopic mechanism through the left connecting member 35 and the right connecting member 36 to form the left and right sides of the filling bulk loading space. On the other hand, when the power output end 21 of the telescopic mechanism contracts, the connection between the left connecting member 35 and the right connecting member 36 and the power output end 21 will not cause too much restriction on the contraction of the power output end 21. In this embodiment, one end of the left connecting member 35 is detachably and fixedly connected to the pull ring on the upper right part of the left side wall panel 31; one end of the right connecting member 36 is detachably and fixedly connected to the pull ring on the upper left part of the right side wall panel 32. The baffle 33 is fixedly installed at the front and rear sides of the measurement area, and the bottom plate 34 is horizontally slidably installed at the bottom of the measurement area.

[0044] Preferably, the baffle 33 is made of a transparent material. In this embodiment, the baffle 33 is made of 1 cm thick acrylic material. The baffle 33 has elevation scales starting from the top of the bottom plate 34.

[0045] Furthermore, as Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, the bottom of the measurement area has a first frame rod 11 and a second frame rod 12 that are parallel to each other and can be selectively spaced apart. In this embodiment, the first frame rod 11 and the second frame rod 12 are detachably and fixedly installed at the bottom of the measurement area through a T-shaped mounting member; the cross-sectional shapes of the first frame rod 11 and the second frame rod 12 are the same, both being stepped, and the first frame rod 11 and the second frame rod 12 are symmetrically installed, that is, the stepped surface of the first frame rod 11 faces left and the stepped surface of the second frame rod 12 faces right. The bottom end of the left side wall plate 31 is rotatably installed on the first frame rod 11, and the bottom end of the right side wall plate 32 is rotatably installed on the second frame rod 12. In this embodiment, the left side wall plate 31 and the right side wall plate 32 are rotatably installed on the first frame rod 11 and the second frame rod 12 by hinges. Specifically, the bottom end of the left side wall plate 31 is fixedly connected to the first leaf of the hinge by bolts, and the second leaf of the hinge is fixedly installed on the right side of the first frame rod 11 through a rectangular connecting plate. The bottom end of the right side wall plate 32 is fixedly connected to the first leaf of the hinge by bolts, and the second leaf of the hinge is fixedly installed on the left side of the second frame rod 12 through a rectangular connecting plate. The left side wall plate 31 and the right side wall plate 32 are symmetrically arranged. It can be understood that using hinges is only a preference, and the same effect can be achieved through other installation structures. The bottom plate 34 includes a first plate body 341 and a second plate body 342 that can slide left and right. The first plate body 341 and the second plate body 342 can slide left and right respectively to abut against any one of the two frame rods, that is, the distance between the first frame rod 11 and the second frame rod 12 can limit the sliding distance of the first plate body 341 and the second plate body 342, and the first plate body 341 and the second plate body 342 can slide to completely overlap each other. The installation plane where the first plate body 341 and the second plate body 342 are located is lower than the installation plane at the bottom ends of the two side wall plates, that is, the positions where the first plate body 341 and the second plate body 342 abut against the frame rods are lower than the installation positions of the bottom ends of the two side wall plates on the frame rods. Thus, the rotation of the two side wall plates is prevented from being affected by the first plate body 341 and the second plate body 342. According to the width of the target stope, the distance between the first frame rod 11 and the second frame rod 12 can be adjusted, and the bottom of the measurement area between the first frame rod 11 and the second frame rod 12 can be closed by the first plate body 341 and the second plate body 342 to form the bottom of the target filling bulk loading space. The bottoms of the first plate body 341 and the second plate body 342 both have handles that facilitate operating their sliding.

[0046] Further, as Figure 1 and Figure 6As shown, the two elastic members are a left elastic rope 41 and a right elastic rope 42 respectively. The upper left side of the left side wall panel 31 is connected to the bottom of the main frame 1 through the left elastic rope 41. The upper right side of the right side wall panel 32 is connected to the bottom of the main frame 1 through the right elastic rope 42. In this embodiment, the first end of the left elastic rope 41 is detachably and fixedly connected to the left bottom of the main frame 1, and the second end of the left connecting member 35 is detachably and fixedly connected to the pull ring on the upper left side of the left side wall panel 31; the first end of the right elastic rope 42 is detachably and fixedly connected to the right bottom of the main frame 1, and the second end of the right connecting member 36 is detachably and fixedly connected to the pull ring on the upper right side of the right side wall panel 32. When the left side wall panel 31 and the right side wall panel 32 are respectively connected to the power output end 21 of the telescopic mechanism through the left connecting member 35 and the right connecting member 36, the left elastic rope 41 and the right elastic rope 42 are in a stretched state. At this time, the left connecting member 35 has a rightward acting force on the left side wall panel 31, the left elastic rope 41 has a leftward acting force on the left side wall panel 31, and the left side wall panel 31 is in a balanced state; the right connecting member 36 has a leftward acting force on the right side wall panel 32, the right elastic rope 42 has a rightward acting force on the right side wall panel 32, and the right side wall panel 32 is also in a balanced state. When the power output end 21 of the telescopic mechanism contracts and is simultaneously disengaged from the left connecting member 35 and the right connecting member 36, the rightward acting force of the left connecting member 35 on the left side wall panel 31 disappears, and the left side wall panel 31 rotates counterclockwise under the action of the left elastic rope 41 until it abuts against the left end of the bottom of the main frame 1; the leftward acting force of the right connecting member 36 on the right side wall panel 32 disappears, and the right side wall panel 32 rotates clockwise under the action of the right elastic rope 42 until it abuts against the right end of the bottom of the main frame 1.

[0047] Further, as Figure 5 and Figure 6 shown, both sides of the left side wall panel 31 and the right side wall panel 32 have end plates that extend perpendicularly to themselves along the side edges. When the left elastic rope 41 and the right elastic rope 42 pull the left side wall panel 31 and the right side wall panel 32 to rotate, they are used to prevent the filled bulk material from flowing out from both sides of the left side wall panel 31 and the right side wall panel 32, playing a role in guiding the flow. The left top end of the left side wall panel 31 and the right top end of the right side wall panel 32 are provided with buffer pads. Thus, it is avoided that the left side wall panel 31 and the right side wall panel 32 are damaged when they abut against the bottom of the main frame 1 under the action of the left elastic rope 41 and the right elastic rope 42.

[0048] Further, as Figure 1 shown, a counterweight 13 is fixed to the bottom of the main frame 1. Because it is necessary to instantaneously release the restrictions on the left and right sides of the filled bulk material loading space, the elastic force of the elastic rope used is relatively high. When the left side wall panel 31 and the right side wall panel 32 abut against the bottom of the main frame 1 under the action of the left elastic rope 41 and the right elastic rope 42, the acting forces transmitted by the left side wall panel 31 and the right side wall panel 32 to the bottom of the main frame 1 are relatively large. Thus, the counterweight 13 is used to avoid the influence of the acting force on the measurement result.

[0049] Example 2:

[0050] This embodiment provides a method for using the device for measuring the acting range of backfill bulk solids on an inclined sidewall described in Example 1, including the steps:

[0051] S1. According to the width of the target stope and the inclination degrees of the hanging wall surrounding rock and the footwall surrounding rock of the stope, construct a target backfill bulk solid loading space formed by the backfill bulk solid measuring assembly, and the force application mechanism 2 and the two connecting members are in a joined state. Specifically, according to the width of the target stope, adjust the distance between the first frame rod 11 and the second frame rod 12, and close a part of the bottom of the measuring area between the first frame rod 11 and the second frame rod 12 through the first plate body 341 and the second plate body 342 to form the bottom of the target backfill bulk solid loading space. Then start the telescopic mechanism to extend the power output end 21 through the top of the main frame 1 into the measuring area. According to the inclination degrees of the hanging wall surrounding rock and the footwall surrounding rock of the target stope, adjust the inclination angles of the left sidewall plate 31 and the right sidewall plate 32, and connect the power output end 21 through the connection ends of the left connecting member 35 and the right connecting member 36. The left elastic rope 41 and the right elastic rope 42 are in a stretched state, and the left sidewall plate 31 and the right sidewall plate 32 are positioned to form a target backfill bulk solid loading space with an upward opening. Among them, neither the left connecting member 35 nor the right connecting member 36 has elasticity, so as to avoid changing the positioning inclination angles of the left sidewall plate 31 and the right sidewall plate 32 when filling the target backfill bulk solids into the backfill bulk solid loading space, resulting in too large data measurement errors.

[0052] S2. Add the target backfill bulk solids into the target backfill bulk solid loading space until the upper surface of the leveled target backfill bulk solids reaches the designed height.

[0053] S3. Drive the force application mechanism 2 and the two connecting members to synchronously enter the disengaged state from the engaged state. Specifically, drive the telescopic mechanism to contract the power output end 21. The connection ends of the left connecting member 35 and the right connecting member 36 with the power output end 21 will abut against the inner wall of the top of the main frame 1 as the power output end 21 contracts. The power output end 21 continues to contract until it disengages from the connection ends of the left connecting member 35 and the right connecting member 36. The left side wall plate 31 quickly rotates counterclockwise under the action of the left elastic rope 41 until the buffer pad of the left side wall plate 31 abuts against the left end of the bottom of the main frame 1. The right side wall plate 32 quickly rotates clockwise under the action of the right elastic rope 42 until the buffer pad of the right side wall plate 32 abuts against the right end of the bottom of the main frame 1. Due to the sudden removal of the restrictions on the left and right sides of the filling bulk carrier space, part of the target filling bulk will flow out of the filling bulk carrier space as the left side wall plate 31 and the right side wall plate 32 scatter. After the scattered flow stops, the target filling bulk remaining in the filling bulk loading space will form a natural angle of repose. According to the weight of the filling bulk flowing out from the left side wall plate 31 and the right side wall plate 32 and the natural angle of repose formed by the remaining filling bulk in the filling bulk loading space, the action range of the target filling bulk on the inclined side wall under the target stope working conditions and the target filling bulk height can be obtained.

[0054] This embodiment provides a method for using the device for measuring the action range of filling bulk on an inclined side wall described in Embodiment 1. By forming a filling bulk loading space through the filling bulk measuring assembly, the working conditions of different stopes are simulated. By filling the filling bulk into the filling bulk loading space, the filling situation of the filling bulk in the stope is simulated, and the applicable range is wide. Then, the restrictions on the left and right sides of the filling bulk loading space are instantaneously removed by the force application mechanism 2 and the elastic members. The action range of the filling bulk on the inclined side wall can be obtained based on the weight of the filling bulk scattered outside the filling bulk loading space and the natural angle of repose formed by the remaining filling bulk in the filling bulk loading space. This method can measure a wide range and has high measurement accuracy.
