DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the following further describes the present application in detail with reference to the accompanying Figures 1 to 3 drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] An embodiment of the present application discloses a method for controlling the effect of liquid oxygen fracturing. Refer to Figure 1 , the method for controlling the effect of liquid oxygen fracturing includes the following steps: Step 101, obtain a pre-fracture image of the fracture area before liquid oxygen fracturing and a post-fracture image after liquid oxygen fracturing.

[0028] Among them, the fracture area refers to the operation area corresponding to liquid oxygen fracturing. In one example, the fracture area includes the area where the bench to be mined is located.

[0029] In one example, both the pre-fracture image and the post-fracture image are collected by a high-definition camera set at a distance, and the parameters of the camera are fixed during the image collection process, so as to facilitate the comparison of the post-fracture image with the pre-fracture image in the later stage.

[0030] In another example, the pre-fracture image and the post-fracture image are collected by a drone. Specifically, when collecting the image, control the drone to fly to the airspace obliquely above the front direction of the free surface of the fracture area, and appropriately adjust the angle of the drone camera to collect the panoramic view of the fracture area.

[0031] In actual implementation, the images before and after mining can also be collected by different methods. For example: collected by an image collection device held by a construction worker at a distance, as long as the image corresponding to the fracture area can be collected.

[0032] Step 102, compare and analyze the post-fracture image with the pre-fracture image to obtain at least one fracture effect index.

[0033] Among them, the fracture effect index is used to indicate the actual effect of liquid oxygen fracturing.

[0034] Optionally, the fracture effect index includes the ore form. Specifically, the ore form is used to indicate the form of the ore obtained by fracturing, and is generally determined based on the projected area or volume of the ore.

[0035] Correspondingly, comparing and analyzing the post-fracture image with the pre-fracture image to obtain at least one fracture effect index includes: comparing and analyzing the post-fracture image with the pre-fracture image to obtain the ore area; intercepting the image corresponding to the ore area in the post-fracture image to obtain the ore image; evaluating the form of the ore in the ore area based on the ore image to obtain the ore form.

[0036] Among them, the ore area contains the ore obtained by liquid oxygen fracturing. Specifically, during the process of fracturing the fracture area, the liquid oxygen will turn into gaseous oxygen and thus rapidly heat up and expand, which will cause the free surface to break into ore and fall off. The area corresponding to the fallen ore is the ore area. In actual implementation, the fallen ore may be scattered in different positions, so the maximum value of the fracture area can be set based on the actual situation.

[0037] In one example, the morphology of the ore within the ore region is evaluated based on the ore image to obtain the ore morphology, including: determining the sample ore from the ore within the ore region based on the ore image; and determining the ore morphology based on the morphology of the sample ore. For example, the average projected area of the sample ore can be determined as the ore morphology, or alternatively, the maximum projected area and / or the minimum projected area of the sample ore can be determined as the ore morphology; Among them, the sample ore can be determined randomly, or the ore region can be divided into several sampling regions, and then the ore selected from each sampling region is used as the sample ore. This embodiment does not limit the determination method of the sample ore.

[0038] Furthermore, the fracturing effect index also includes the ore distribution. Specifically, the ore position is used to describe the distribution of the ore, and is generally determined based on the relative position relationship between the ore and the free surface of the fracturing zone and / or the relative position relationship between the ores.

[0039] Correspondingly, after obtaining the ore region, it further includes: determining the ore distribution based on the ore image.

[0040] In one example, determining the ore distribution based on the ore image includes: determining the ore density within the region based on the ore image; and determining the ore density as the ore distribution. Specifically, the position where ore exists and the position where no ore exists within the ore region can be analyzed from the ore image, and then the ratio of the area corresponding to the position where ore exists to the total area of the ore region is determined as the ore density.

[0041] In another example, determining the ore distribution based on the ore image includes: determining a reference position from the ore region based on the ore image; determining the reference distance between the reference position and the free surface of the fracturing zone; and determining the reference distance as the ore distribution. Specifically, the reference position can be the geometric center of the ore region, or alternatively, the position corresponding to the ore with the largest projected area within the ore region.

[0042] In other examples, the ore distribution can also be determined comprehensively by combining the ore density and the reference distance. For example, the product of the comprehensive distance and the ore density is determined as the ore distribution. In this way, the ore distribution can reflect both the relative position relationship between the ores and the relative position relationship between the ore and the free surface, and thus the reference value of the ore distribution can be improved.

[0043] In actual implementation, the fracturing effect index can also be represented by other means. For example, the fracturing effect index includes the change situation of the free surface before and after fracturing, the flatness of the fracturing surface, etc., as long as it can reflect the fracturing effect.

[0044] Step 103: Determine the difference in fracturing effect based on the matching relationship between the fracturing effect index and the expected effect.

[0045] In one example, the difference in fracturing effect includes morphological differences. Correspondingly, determining the difference in fracturing effect based on the matching relationship between the fracturing effect index and the expected effect includes: determining whether the ore morphology matches the expected morphology; in the case where the ore morphology does not match the expected morphology, determining the morphological difference based on the difference between the ore morphology and the expected morphology; in the case where the ore morphology matches the expected morphology, determining that there is no morphological difference.

[0046] In one instance, the ore morphology is represented by the average projected area. Correspondingly, the expected morphology is represented by the expected projected area. At this time, determining whether the ore morphology matches the expected morphology includes: determining whether the gap value between the average projected area and the expected projected area is less than or equal to the gap value threshold; if so, determining that the ore morphology matches the expected morphology; if not, determining that the ore morphology does not match the expected morphology.

[0047] Further, in the case where it is determined that the ore morphology does not match the expected morphology, it can be determined whether the average projected area is less than the expected projected area; if so, determining that the ore volume is small; if not, determining that the ore volume is large. Even further, the absolute value of the difference between the average projected area and the expected projected area can be determined, which can help assist in judging the amplitude of the adjustment of the fracturing parameters.

[0048] In another example, the difference in fracturing effect includes distribution differences. Correspondingly, determining the difference in fracturing effect based on the matching relationship between the fracturing effect index and the expected effect includes: determining whether the ore distribution matches the expected distribution; in the case where the ore distribution does not match the expected distribution, determining the distribution difference based on the difference between the ore distribution and the expected distribution; in the case where the ore distribution matches the expected distribution, determining that there is no distribution difference.

[0049] In one instance, the ore distribution is determined based on the ore density and the reference distance. At this time, determining whether the ore distribution matches the expected distribution includes: determining whether the ore distribution is less than or equal to the expected distribution; if so, determining that the ore distribution matches the expected distribution; if not, determining that the ore distribution does not match the expected distribution.

[0050] Further, in the case where it is determined that the ore distribution does not match the expected distribution, the relationship between the reference distance and the preset distance and the relationship between the ore density and the reference density can be further determined to find out the reason why the ore distribution does not match the expected distribution, which can then help assist in judging the method and amplitude of the adjustment of the fracturing parameters.

[0051] Step 104: Adjust the fracturing parameters used in the liquid oxygen fracturing process based on the differences in fracturing effects, so as to use the adjusted fracturing parameters for liquid oxygen fracturing in subsequent liquid oxygen fracturing processes.

[0052] In one example, the fracturing parameters include the oxygen filling amount per single pipe. The oxygen consumption per single pipe is used to indicate the oxygen filling for the fracturing pipe. Correspondingly, adjusting the fracturing parameters used in the liquid oxygen fracturing process based on the differences in fracturing effects includes: adjusting the oxygen filling amount per single pipe in the case of morphological differences. Specifically, the oxygen filling amount per single pipe can be increased when the morphological differences indicate a larger ore volume; the oxygen filling amount per single pipe can be decreased when the morphological differences indicate a smaller ore volume.

[0053] In another example, the fracturing parameters include the hole pattern parameters. The hole pattern parameters are used to indicate the hole pattern planning for the fracturing area. Correspondingly, adjusting the fracturing parameters used in the liquid oxygen fracturing process based on the differences in fracturing effects includes: adjusting the hole pattern parameters in the case of distribution differences. Specifically, the hole spacing can be increased when the reference distance is greater than the preset distance; the hole spacing can be decreased when the ore density is less than the reference density.

[0054] In actual implementation, the differences in fracturing effects can further include specific difference values, such as: the absolute value of the difference between the average projected area and the expected projected area. At this time, the adjustment amplitude of the fracturing parameters can be further determined based on the difference value, which can help improve the accuracy of adjusting the fracturing parameters.

[0055] Optionally, vibration velocity monitors are also installed at the monitoring positions of the fracturing area (such as positions 50 meters and 100 meters away from the fracturing area). At this time, the fracturing parameters can be further adjusted in combination with the vibration velocity during the fracturing process monitored by the vibration velocity monitors, which can help control the vibration velocity during the fracturing process.

[0056] The implementation principle of a method for controlling the effect of liquid oxygen fracturing in an embodiment of the present application is as follows: Obtain the pre-fracture image of the fracture zone before liquid oxygen fracturing and the post-fracture image after liquid oxygen fracturing; Compare and analyze the post-fracture image with the pre-fracture image to obtain at least one fracture effect index; Determine the fracture effect difference based on the matching relationship between the fracture effect index and the expected effect; Adjust the fracture parameters used in the liquid oxygen fracturing process based on the fracture effect difference, so as to perform liquid oxygen fracturing using the adjusted fracture parameters in subsequent liquid oxygen fracturing processes. By adopting the above technical solution, the fracture effect difference can be determined based on the matching relationship between the fracture effect index obtained by comparing and analyzing the post-fracture image and the pre-fracture image and the expected effect, and the fracture parameters used in the liquid oxygen fracturing process can be adjusted based on the fracture effect difference. In this way, the liquid oxygen fracturing process can be dynamically adjusted based on the actual fracture effect, which can help improve the accuracy of the liquid oxygen fracturing process.

[0057] In some embodiments, the fracture parameters include hole pattern parameters. Refer to Figure 2 , step 101, obtaining the pre-fracture image of the fracture zone before liquid oxygen fracturing and the post-fracture image after liquid oxygen fracturing, includes: Step 201, obtaining the pre-fracture image.

[0058] Step 202, perform hole position planning on the fracture zone based on the pre-fracture image and the hole pattern parameters to obtain hole pattern data, so as to guide the construction personnel to drill holes at the blast hole positions in the fracture zone.

[0059] Among them, the hole pattern parameters are used to indicate the hole pattern planning for the fracture zone. Specifically, the hole pattern parameters may include factors related to determining the drilling positions such as hole spacing and row spacing. Further, the hole pattern parameters may also include parameters related to the drilling process such as blast hole depth, drilling overdepth, and drilling diameter, so as to accurately guide the determination of the hole pattern data. In actual implementation, the hole pattern parameters can be fixedly set according to actual needs. Further, the hole pattern parameters can also be adjusted according to the actual fracture effect.

[0060] The hole pattern data is used to indicate the positions of the blast holes. In one example, the positions of the blast holes are represented by the coordinates of the blast holes.

[0061] In one example, the expected effect includes the expected mining volume. Performing hole position planning on the fracture zone based on the pre-fracture image and the hole pattern parameters to obtain hole pattern data includes: Modeling based on the pre-fracture image to obtain the pre-fracture model of the fracture zone; Performing hole position planning on the pre-fracture model based on the expected mining volume and the hole pattern parameters to obtain hole pattern data.

[0062] In one example, the number of blast holes can be determined based on the expected extraction volume, and then, based on the number of blast holes and the hole pattern parameters, hole position planning can be carried out on the pre-fracture model to obtain hole pattern data. Specifically, blast holes are generally planned in a staggered pattern. Therefore, given the number of blast holes and the hole pattern parameters, the hole pattern data can be obtained conveniently.

[0063] Step 203: Control the ignition of the fracturing pipes installed at the blast hole positions.

[0064] Specifically, after drilling the blast holes in the fracturing area according to the hole pattern parameters, the fracturing pipes need to be installed in the blast holes, and an ignition head is reserved in the fracturing pipes. During the ignition process, control the ignition head to ignite, so that the liquid oxygen is ignited, thereby achieving the fracturing effect.

[0065] Optionally, the fracturing parameters further include the liquid oxygen consumption per single pipe. Before controlling the ignition of the fracturing pipes installed at the blast hole positions, it further includes: planning the oxygen filling method based on the liquid oxygen consumption per single pipe and the hole pattern data to obtain oxygen filling data, so as to guide the construction personnel to fill oxygen into the fracturing pipes installed at the blast hole positions.

[0066] In actual implementation, in order to shorten the residence time of the liquid oxygen in the fracturing pipes, different fracturing pipes are filled with liquid oxygen simultaneously. Therefore, it is necessary to estimate the flow rate and oxygen filling amount (or oxygen filling duration) of the liquid oxygen based on the liquid oxygen consumption per single pipe and the number of blast holes recorded in the hole pattern data, so as to control the oxygen filling method.

[0067] In actual implementation, the liquid oxygen consumption per single pipe can be set according to experience and can be adjusted according to the actual fracturing effect.

[0068] In the above technical solution, since the oxygen filling data can be planned in combination with the hole pattern data, it can help to provide accurate guidance for the oxygen filling process, and further help to accurately control the liquid oxygen fracturing process.

[0069] Step 204: Obtain the post-fracture image.

[0070] In the above technical solution, since the hole position planning of the fracturing area can be carried out based on the pre-fracture image and the hole pattern parameters to obtain the hole pattern data, it can accurately lead to the drilling of the blast holes and the installation of the fracturing pipes, and further help to achieve the accurate control of the liquid oxygen fracturing process.

[0071] Based on the above technical solution, further, the fracturing parameters used in the liquid oxygen fracturing process are adjusted based on the difference in fracturing effects, including: quantifying the difference in fracturing effects into a fuzzy value through a predefined membership function; performing fuzzy inference on the fuzzy value of the difference in fracturing effects according to the rule base to obtain the fuzzy value of the fracturing parameter adjustment suggestion; defuzzifying the fuzzy value of the fracturing parameter adjustment suggestion to obtain the fracturing parameter adjustment suggestion; and adjusting the fracturing parameters based on the fracturing parameter adjustment suggestion.

[0072] Among them, the membership function can be a triangular membership function, a trapezoidal membership function, a Gaussian membership function, etc., as long as it can realize the fuzzification of variables.

[0073] The rule base consists of a series of rules, and each rule is used to indicate the fuzzy value of the parameter adjustment suggestion under different differences in fracturing effects. In one example, the rule base can be preset according to actual experience and test results. Specifically, the rule adopts "if... (condition), then... (fracturing parameter adjustment suggestion)", where the condition can be set in combination with the fuzzy values corresponding to at least one difference in fracturing effects. For example: if the distribution difference is small and the shape difference is large, then the hole spacing is reduced; another example: if the distribution difference is large and the shape difference is small, then the single-tube oxygen filling amount is reduced. In actual implementation, the rules in the rule base can be updated and adjusted during actual use to enhance the accuracy and adaptability of the rules.

[0074] The specific method of fuzzy inference includes: for each rule in the rule base, determining the fuzzy value of the fracturing parameter adjustment suggestion corresponding to the rule based on the fuzzy value of the difference in fracturing effects in the condition of the rule; and determining the fuzzy value of the final fracturing parameter adjustment suggestion based on the fuzzy value of the fracturing parameter adjustment suggestion corresponding to each rule. Specifically, the maximum value of the fracturing parameter adjustment suggestions of all rules can be finally determined as the fuzzy value of the fracturing parameter adjustment suggestion, or the centroid of the fracturing parameter adjustment suggestions of all rules can also be finally determined as the fuzzy value of the fracturing reference adjustment suggestion.

[0075] Defuzzification is the process of converting the inferred fuzzy value into a specific numerical value. In actual implementation, it can be achieved by methods such as the maximum membership degree method and the centroid method. Taking the centroid method as an example, the centroid of different fuzzy sets (such as: increase, remain unchanged, decrease) of the fracturing reference suggestion can be calculated, and the final fracturing parameter adjustment suggestion can be calculated based on the fuzzy value and centroid of the fracturing reference suggestion on different fuzzy sets.

[0076] In the above embodiments, the difference in fracturing effects can be analyzed through fuzzy inference to obtain suggestions for adjusting the fracturing parameters, and the fracturing parameters can be adjusted based on the suggestions for adjusting the fracturing parameters. This can help to comprehensively analyze the differences in different fracturing effects, thereby helping to improve the accuracy of adjusting the fracturing parameters, and further helping to achieve precise control of the fracturing effects.
