由煤科总院北京开采所、国家地震局地壳应力研究所、新汶矿务局共同承担完成的“煤矿井下地应力测试技术及其在锚杆支护中的应用”课题,已于1997年12月26日通过煤炭部科教司的技术鉴定.该成果首次全面深入地研究了煤矿井下地应力测试方法及与锚杆支护之间的关系.确定了压磁套芯解除法结合地质测绘法为煤矿井下地应力测试方法.研制出YJ-95型压磁全应力计,实现了三维地应力的单孔测量.研制出与压磁全应力计相配套的测试仪器,且具有测量快捷、精度高、测值稳定等特点.建立了以地应力为基础的锚杆支护设计方法,编制了煤巷锚杆支护设计软件.较准确地实测了两个矿
The project entitled “Underground Stress Testing Technology in Coal Mine and Its Application in Anchor Support” jointly undertaken by Beijing Mining Institute of China Coal Research Institute, Institute of Crustal Stress of State Seismological Bureau and Xinwen Mining Bureau was completed in 1997 December 26 by the Ministry of Science and Technology Division of the technical appraisal.The results for the first time a comprehensive and in-depth study of underground coal mine stress testing methods and the relationship between the bolt support.Determined that the pressure magnetic core lifting method combined with geological mapping method For the underground stress test method of coal mine.YJ-95-type pressure magnetic full stress meter was developed, to achieve the three-dimensional geostress single hole measurement.Combined with the pressure magnetic full stress test instrument, and has the measurement speed, accuracy High and stable measurement value, etc. The design method of rock bolt support based on geo-stress was established and the software of rock bolt support design was compiled.The two mines
