摘要
根据砚北煤矿矿井动力现象的特征,通过现场资料统计、大量的煤岩力学性质试验及现场地应力测试等,分析了矿井动力现象的性质、发生机理,在此基础上进行了危险性评价,并提出了相应的治理方案。
On the base of found feature of Yan-bei coal mine's dynamic phenomena and initial statistics analysis and lots of coal and rock mechanics experiments and the measuring of ground stress, the author analyses the nature and mechanism of the dynamic phenomena, also the author makes the hazard evaluation and suggest regulated plans to work safely.
