不规则工作面综合物探设计施工方法研究

Study on comprehensive geophysical exploration design and construction method of irregular working face

煤矿工作面布置过程产生的三角煤、地质复杂地区沿断层等地质构造圈定的工作面、采掘生产遗留的煤柱工作面,均会产生相对不规则的工作面。本文以羊东矿为例通过对比不规则工作面和规则工作面形态之间的区别,结合综合物探常用的瞬变电磁和无线电波坑道透视探测原理及现场施工技术,从理论出发完成初步设计,后依据现场实际施工条件来设置物探布置形式,保证工作面防治水和地质工作要求,为煤矿安全生产提供保证。

The triangular coal generated in the process of coal mine working face layout,the working face delineated by geological structures such as faults in complex geological areas,and the coal pillar working face left by mining and excavation could produce relatively irregular working faces.Talking Yangdong Mine as an example,by comparing the difference between irregular working face and regular working face,combined with comprehensive geophysical exploration including the transient electromagnetic and radio wave tunnel perspective detection principle and field construction technology,the preliminary design was completed based on the theory,then the geophysical exploration layout was set up according to the actual construction conditions,which ensured the working face water prevention and control and geological work requirements,and provided guarantee for coal mine safety production.
