在改进套筒致裂装置性能的基础上，使压力-体积曲线的记录与处理得到改善，对潘三矿东采区的测试实践表明，得出的压力-体积曲线较好地反映了钻孔围岩随内压增加所表现出的力学性质。还探讨了如何通过改进套筒致裂技术来实现由围岩应力测试发展到原岩应力测试以及围岩损伤区的测定。
On the basis of improving the performance of the sleeve fracturing device, the recording and processing of the pressure-volume curve are improved. The test practice in the East Mining Area of Pansan Mine shows that the derived pressure-volume curve better reflects the drilling The mechanical properties of surrounding rock with increasing internal pressure. Also discussed how to improve the sleeve fracturing technology from the development of the surrounding rock stress test to the original rock stress test and the determination of the surrounding rock damage zone.
