摘要
紫晟煤业矿井地质构造复杂,断层、陷落柱极为发育。为合理布置采掘工作面,避免无效掘进进尺,需对断层及陷落柱进行超前预判分析。本文以2-109工作面陷落柱的探查分析为例,运用钻孔探测、坑透验证的方法,论述了陷落柱的探测分析过程,对同类型矿井探查陷落柱发育范围具有一定的借鉴意义。
With faults and collapse columns extremely developed,the geological structure of the Zisheng Coal Mine is complex.In order to rationally arrange the mining face and avoid invalid advancement footage,it is necessary to conduct advanced prediction analysis on faults and collapsed columns.Taking the exploration and analysis of the collapsed column in the 2-109 working face as an example,the article discusses the detection and analysis process of the subsided column by the methods of drilling detection and pit penetration verification,which has certain reference significance for the exploration of the development range of the subsided column in the similar mine.
