[0038] Figure 1It is a schematic flow chart of a rock breaking method supporting composite expansion fracturing provided according to an embodiment of the present application.

[0039] like Figure 1 As shown, the method comprises the following steps:

[0040] Step S101, obtaining the compressive strength and stress-strain curve of the core of the expansion and fracturing hole, and obtaining the crack image around the expansion and fracturing hole, and extracting the crack parameters based on the crack image around the expansion and fracturing hole, and determining the crack complexity according to the crack parameters, wherein the stress-strain curve is a relationship curve between the stress and strain amount of the core;

[0041] Specifically, a drilling rig is used to drill a fracture hole in the rock, and a rock core in the fracture hole is taken out, so that the compressive strength and stress-strain curve of the rock core in the fracture hole can be obtained.

[0042] Step S102, determining a rock fracturing index according to the crack complexity, the compressive strength and the stress-strain curve, classifying the expansion holes according to the rock fracturing index, and determining whether the expansion holes are difficult to fracture or easy to fracture;

[0043] In one embodiment of the present application, the above-mentioned fracture parameters include the ratio of all fracture areas to the core side surface area, the fracture dip angle dispersion, the fracture porosity and the variance of the fracture dip angle. The step S102 of determining the fracture complexity according to the above-mentioned fracture parameters includes:

[0046] The step S102 of determining the rock fracturing index according to the above-mentioned crack complexity, the above-mentioned compressive strength and the above-mentioned stress-strain curve includes:

[0047] according to

[0048] Determine the rock fracturing index above, where B I is the rock fracturing index mentioned above, σ I , σ P and σ R are the crack initiation stress, peak stress and residual stress respectively, and σ I , σP and σ R is the value read from the above stress-strain curve, S I is the above compressive strength, a and b are the height and diameter of the core respectively, F c is the above crack complexity.

[0049] Step S102 classifies the expansion holes according to the rock fracturing index to determine whether the expansion holes are difficult to fracture or easy to fracture holes, including: when the rock fracturing index is greater than or equal to the index threshold, determining the expansion holes as difficult to fracture holes; when the rock fracturing index is less than the index threshold, determining the expansion holes as easy to fracture holes.

[0050] Specifically, the index threshold is greater than or equal to 60MPa. When the rock fracturing index is greater than or equal to the index threshold, the expansion hole is identified as a difficult-to-crack hole. When the rock fracturing index is less than the index threshold, the expansion hole is identified as an easy-to-crack hole, so as to facilitate the subsequent different blasting treatments for the difficult-to-crack holes and the easy-to-crack holes.

[0051] Step S103, when it is determined that the above-mentioned bursting hole is the above-mentioned difficult-to-crack hole, the BIM technology is used to deepen the position of the above-mentioned difficult-to-crack hole, determine the position of the explosive placement hole, and generate a first prompt information to prompt the position of the explosive placement hole.

[0052] In the above steps, the fracturing holes are classified according to the parameters of the core of the fracturing holes, so that different blasting treatments are performed for the hard-to-fract holes and the easy-to-fract holes. In addition, when it is determined that the above-mentioned fracturing holes are the hard-to-fract holes, the positions of the hard-to-fract holes are deepened by using BIM technology, and the positions of the explosive placement holes are determined, thereby improving the rationality of the positions of the explosive placement holes, thereby improving the fracturing effect, and further solving the problem that the existing rock breaking methods cannot be adjusted according to the physical properties of different rock positions and have a low degree of intelligence.

[0053] In one embodiment of the present application, after generating the first prompt information, the method further includes: upon receiving a blasting instruction, detonating the explosives in the explosive placement hole; generating a second prompt information to prompt the need to remove the gravel and the need to drill a hydraulic fracturing groove along the perimeter of the difficult-to-crack hole; upon receiving a fracturing instruction, controlling the hydraulic fracturing machine to hydraulically fracture the interior of the hydraulic fracturing groove.

[0054] Specifically, BIM technology is used to deepen the position of difficult-to-crack holes, determine the positions of explosive placement holes and hydraulic fracturing grooves around the difficult-to-crack holes, drill explosive placement holes around the difficult-to-crack holes and put explosives in according to construction specifications, evacuate personnel for blasting operations, and after the blasting is completed, remove the gravel. At this time, an independent space will be formed in the middle of the explosive placement hole, and hydraulic fracturing grooves will be drilled along the four sides of the difficult-to-crack hole. The inner diameter of the hydraulic fracturing groove is controlled within 10 cm. During the drilling process of the explosive placement holes and hydraulic fracturing grooves, a dust suppression sprayer is placed next to the drilling rig to prevent dust pollution. After the drilling of the fracturing holes is completed, the hydraulic fracturing machine is in place according to the plan, and the hydraulic fracturing machine is started for hydraulic fracturing. After completion, the formation of the fracturing cracks is inspected, and the unqualified ones are fractured again separately. After the fracturing cracks are formed, a crawler hydraulic breaker is used to crush the hard rock within the fracturing cracks. The crawler backhoe excavator is responsible for the removal of the broken rock in the independent foundation. It is strictly forbidden to interfere with the rock layer outside the cracks during cleaning.

[0055] In one embodiment of the present application, after controlling the hydraulic fracturing machine to hydraulically fracture the interior of the hydraulic fracturing groove, the method further includes: upon receiving a re-fracture instruction, controlling the hydraulic fracturing machine to hydraulically fracture the interior of the hydraulic fracturing groove based on the re-fracture instruction.

[0056] Specifically, the unqualified parts are fractured separately again. After the fracture cracks are formed, crawler hydraulic breakers are used to crush the hard rocks within the fracture cracks. Crawler backhoe excavators are responsible for the removal of the broken rocks within the independent foundation. It is strictly forbidden to disturb the rock layer outside the fracture during cleaning.

[0057] In one embodiment of the present application, the method further includes: when it is determined that the rupture hole is the easy-to-break hole, generating a third prompt information to prompt that a limiting sleeve needs to be placed in the easy-to-break hole, and thermite is filled into the easy-to-break hole and outside the limiting sleeve. When the thermite filling height reaches a predetermined height, a remote ignition device is respectively placed into the easy-to-break hole and on both sides of the limiting sleeve, and buffer gravel is filled into the easy-to-break hole and outside the limiting sleeve and compacted to ensure that the limiting sleeve is circumferentially fixed, and dry ice stored in the limiting sleeve is placed in the easy-to-break hole. The storage is placed in the above-mentioned limiting sleeve so that the above-mentioned dry ice storage slides into the bottom of the limiting sleeve, and then the sealing material is continued to be filled to the end of the limiting sleeve, and then the thermite is continued to be filled until the thermite filling height is higher than the dry ice storage filling height, and then the buffer gravel is filled into the above-mentioned limiting sleeve, and then the sealing material is continued to be filled to the end of the above-mentioned limiting sleeve, compacted, and a sealing plate is added on the above-mentioned crack-prone holes to completely cover the crack-prone holes, and soil is added and compacted; when the protection work completion instruction is received, the above-mentioned remote ignition device is detonated.

[0058] Specifically, a limiting sleeve is placed in the crack-prone hole, the limiting sleeve is a hard plastic tube, and the thermite is filled into the crack-prone hole and outside the limiting sleeve. When the thermite filling height reaches a predetermined height, a remote ignition device is respectively placed into the crack-prone hole and on both sides of the limiting sleeve. The remote ignition device includes a packaging bag, a wireless remote ignition device body packaged in the packaging bag, and a combustible mixture filled in the packaging bag. Buffer gravel is filled into the crack-prone hole and outside the limiting sleeve and compacted to ensure that the limiting sleeve is fixed circumferentially. A dry ice storage container containing dry ice is quickly placed into the limiting sleeve so that it slides into the bottom of the limiting sleeve, and then continues Fill the sealing material to the end of the limiting sleeve, and then continue to fill thermite until the thermite filling height is slightly higher than the dry ice storage filling height, and then quickly fill the limiting sleeve with buffer gravel. The first buffer gravel filling amount accounts for one-third of the remaining filling area in the blasting hole, and the second buffer gravel filling amount accounts for one-third of the remaining filling area in the limiting sleeve. Then continue to fill the sealing material to the end of the limiting sleeve, compact it, cover the cracks with sealing plates to completely cover the cracks, add soil, tamp it, all personnel evacuate to a safe point, start the remote ignition device, ignite the blasting, and after the blasting, clean up the gravel and residue in the cracks.

[0059] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the rock breaking method of supporting composite expansion fracturing of the present application will be described in detail below in combination with specific embodiments.

[0060] This embodiment relates to a specific rock breaking method using supported composite expansion fracture, such as Figure 2 As shown, the following steps are included:

[0061] Step S1: Obtain the compressive strength and stress-strain curve of the core of the expansion hole, obtain the crack image around the expansion hole, extract the crack parameters based on the crack image around the expansion hole, and determine the crack complexity according to the crack parameters. The stress-strain curve is a relationship curve between the stress and strain of the core;

[0062] Step S2: determining the rock fracturing index according to the crack complexity, compressive strength and stress-strain curve, classifying the expansion and fracturing holes according to the rock fracturing index, and determining whether the expansion and fracturing holes are difficult to fracture holes or easy to fracture holes;

[0063] Step S3: when it is determined that the expansion-fracture hole is a difficult-fracture hole, the BIM technology is used to deepen the position of the difficult-fracture hole, determine the position of the explosive placement hole, and generate first prompt information to prompt the position of the explosive placement hole;

[0064] Step S4: upon receiving a blasting instruction, detonating the explosives in the explosive placement hole; generating a second prompt message to prompt that the gravel needs to be removed and that a hydraulic fracturing groove needs to be drilled along the perimeter of the difficult-to-fracture hole; upon receiving a fracturing instruction, controlling the hydraulic fracturing machine to hydraulically fracture the interior of the hydraulic fracturing groove; upon receiving a re-fracturing instruction, controlling the hydraulic fracturing machine to hydraulically fracture the interior of the hydraulic fracturing groove based on the re-fracturing instruction;

[0065] Step S5: When it is determined that the rupture hole is an easy-to-break hole, a third prompt message is generated to prompt that the limit sleeve needs to be placed in the easy-to-break hole, and thermite is filled into the easy-to-break hole and outside the limit sleeve. When the thermite filling height reaches a predetermined height, a remote ignition device is placed in the easy-to-break hole and on both sides of the limit sleeve respectively, and buffer gravel is filled into the easy-to-break hole and outside the limit sleeve and compacted to ensure that the limit sleeve is fixed circumferentially, and a dry ice storage container containing dry ice is placed in the limit sleeve. The dry ice storage container is inserted into the bottom of the limiting sleeve, and then the sealing material is continued to be filled to the end of the limiting sleeve, and then the thermite is continued to be filled until the thermite filling height is higher than the dry ice storage container filling height, and then the buffer gravel is filled into the limiting sleeve, and then the sealing material is continued to be filled to the end of the limiting sleeve, compacted, and a sealing plate is added to the crack-prone hole, so that the crack-prone hole is completely covered, and soil is added and compacted; when the protection work is completed, the remote ignition device is detonated.

[0066] By using a drilling rig to drill expansion holes in the rock, taking out the rock core from the expansion holes, obtaining the compressive strength and stress-strain curve of the rock core, collecting crack images around the expansion holes, extracting crack parameters, calculating crack complexity, and calculating the rock fracturing index based on the crack complexity, compressive strength and stress-strain curve. According to the rock fracturing index, the expansion holes are classified to obtain easy-to-crack holes and difficult-to-crack holes. The BIM technology is used to deepen the position of the difficult-to-crack holes, determine the positions of the explosive placement holes and hydraulic fracturing grooves around the difficult-to-crack holes, and carry out blasting operations. After the blasting is completed, the hydraulic fracturing grooves are drilled along the perimeter of the difficult-to-crack holes, and the hydraulic fracturing machine is started for hydraulic fracturing. After the completion of the blasting, the formation of the expansion cracks is checked. After the expansion cracks are formed, the gravel in the cracks is removed, the limiting casing is placed in the easy-to-crack hole, and the thermite is placed in the easy-to-crack hole or outside the limiting casing. A remote ignition device and a dry ice storage device storing dry ice are then used, and sealing materials are then continuously filled to the end of the limiting sleeve, and then thermite, buffer gravel and sealing materials are continuously filled to the end of the limiting sleeve, compacted, and ignited for blasting. After blasting, gravel and residues in the cracks are cleaned, and the rocks are classified according to their physical properties at different locations. A dual rock breaking method of hydraulic pressure and blasting is used for locations that are difficult to crack, and a dry ice blasting method is used for locations that are prone to cracking. The rock can be broken according to the physical properties of the rocks at different locations, and the degree of intelligence is high. At the same time, the dry ice blasting method utilizes the large amount of heat released by the thermite reaction to sublimate the dry ice, so as to utilize the rapid expansion of the dry ice volume to achieve the purpose of cracking the rock mass, and the safety is greatly improved. The thermite reaction is close to the wall of the blasting hole, which will greatly heat the rock mass, and the subsequent sudden cooling after the dry ice sublimates will cause uneven local heating of the rock mass, thereby achieving the effect of enhancing the cracking.

[0067] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.
