摘要
以王家岭煤矿首采区物探解释的CK2、CK6采空区为例,分析了采空区物探特征,根据煤矿区地质、水文地质特征,结合小煤窑的分布及开采特征,利用钻探手段对采空区进行了验证。在验证时,主要考虑了钻探、煤层厚度、简易水文、区域含水层水位、裂隙含水层富水性5个方面的影响因素。结果表明,物探解释的采空区是可靠的,并且查明了采空区的起止深度及其积水情况。对煤矿的巷道布设、井下探放水的实施和安全开采具有一定的指导意义。
Taking the Wangjialing coalmine first winning district CK2, CK6 gob areas geophysical interpretation as example, analyzed gob area geophysical prospecting characteristics. According to coalmine area geological, hydrogeological characteristics, combined with small coalmine distribution and extracting characteristics, using drilling means carried out gob area verification. In the verification, 5 aspects of impacting factors including drilling, coal seam thickness, facilitated hydrogeological observation, regional aquifer water-table, fissure aquifer water yield property are mainly considered. The result has demonstrated that, gob area geophysical interpretation is reliable, and can find out gob area start-close depths and ponding situation as well. Thus have certain guiding significance in coalmine roadway layout, underground water detection and drainage bring into effect and safe mining.
