Abstract: The disclosure provides a variable dip fault slip simulation test method, which relates to the technical field of indoor simulation test of underground engineering. The variable dip fault slip simulation test method of the disclosure adopts a sample device and a loading device, which includes the following steps: Step 1. sample preparation; Step 2. sample assembly; Step 3. loading preparation; Step 4. sample loading. The variable dip fault slip simulation test method of the disclosure can prepare rock like samples with different dip interfaces, simulate the slip failure process of faults with different dip angles, as well as the normal dip slip and reverse dip slip of faults, facilitate the operation of slip simulation test, and collect test data automatically and accurately.

Abstract: A collaborative erosion-control method of releasing-splitting-supporting based on coal mass pressure relief and roof pre-splitting provided by the disclosure includes the following steps: step 1, driving into a coal seam to release pressure; step 2, low roof pre-splitting during driving process; step 3, supporting of roadway surrounding rock and support reinforcement; step 4, floor destressing of the roadway; step 5, high roof pre-splitting before mining; step 6, destressing and supporting of the advanced roadway surrounding rock during the mining process of the working face. The collaborative erosion-control method of releasing-splitting-supporting based on coal mass pressure relief and roof pre-splitting, and to carry out local pressure relief, roof pre-splitting and reinforcement support construction in the whole cycle of the coal working face in a progressive manner, so as to achieve the prevention and control of rock burst in the working face.
