摘 要:随着煤矿开采深度的不断增加,冲击地压已成为煤矿开采的重大隐蔽灾害之一。影响冲击地压的因素有客观地质条件方面和人为开采技术条件两方面的双重因素叠加。在煤炭资源勘查过程中应加强从地质条件因素影响方面对冲击地压的评价研究工作,预先对冲击地压发生的可能性及强度等级作出分析。本文以宁夏南部南湾勘查区煤炭资源勘探过程中冲击地压评价研究为例,采用地质因素影响下的冲击地压危险性指数法对勘查区主要可采煤层5煤以上100m范围内冲击地压危险性进行了评价,冲击地压危险性指数为0.5,冲击地压危险状态等级评定为弱冲击危险性,为南湾矿井规划建设设计和建立防冲体系提供一定的的地质资料服务。With the increasing depth of coal mining,Rock burst has become one of the major hidden disasters in coal mining.The factors affecting Rock burst are the superposition of two factors,namely,objective geological conditions and artificial mining technical conditions.In the process of coal resource exploration,we should strengthen the evaluation and research of Rock burst from the influence of geological conditions,and analyze the possibility and intensity level of Rock burst in advance.Taking the evaluation study of Rock burst in the process of coal resource exploration in Nanwan exploration area in southern Ningxia as an example,this paper evaluates the risk of Rock burst within 100 m above the fifth coal seam in the exploration area by using the risk index method of Rock burst under the influence of geological factors.The risk index of Rock burst is 0.5,and the risk level of Rock burst is assessed as weak rockburst risk,Provide certain geological data services for the planning,construction,design,and establishment of a erosion prevention system of the Nanwan Mine.
