综合物探方法在小煤矿采空区探测中的应用

Application of Comprehensive Geophysical Method in the Detection of Goaf in Small Coal Mines

鉴于小煤矿开采技术和管理落后,采空区资料缺乏,给采掘作业过程带来了积水、积气、塌陷等许多重大安全隐患。为了给煤矿安全生产提供保障,提高工作效率,降低安全成本,需研究除巷探、钻探外,利用物探手段探明采空区的分布范围及其积水情况的技术,促使煤矿安全生产得到保证。

Small coal mines have been merged and reorganized after a new round of resource integration in Shanxi Province. Due to backward mining technology and management of small coal mines and the lack of resource in the goaf, there exists many major safety hazards such as water accumulation, gas accumulation and collapse in mining operation process. The paper puts forward geophysical method to explore the distribution of the goaf and its water accumulation, which guarantees safety production of coal mines, improves work efficiency and reduces safety costs.
