摘要
在开滦赵各庄矿冲击地压现场调研的基础上,总结了近10年来该矿开采千米深度时发生2次严重的冲击动力灾害的特征;对煤岩材料进行了力学参数和冲击倾向性实验测定,并从地质、技术、岩性、地震等方面分析了动力灾害的诱发因素,进而与大同忻州窑矿、抚顺老虎台矿做了对比分析,认为矿井冲击地压的发生均有其主导的诱发因素,这也为赵各庄矿和其他矿井冲击地压防治提供了方法。
Base on the site investigation of the pressure bumping in Zhaogezhuang Mine of Kailuan Group, the paper summarized the features of two serious bumping disasters occurred in underground mine with a depth of 1000 meters of the mine in the passed 10 years. A mechanics parameters and bumping tendency were tested and measured. The induced factors of the dynamic disasters were analyzed from the geology, technology, rock property and earthquake. In the comparison with the monitoring and measurements of Datong Xinzhouyao Mine and Fushun Laohutai Mine, the paper hold that the mine pressure bumping occurred shall have the main induced factors.
