摘要
为分析贵州山区煤矿开采对地表的影响,采用钻探、声波测井、地面监测等方法,根据钻探工程揭露的地下水位、声波测井查明的采空区上覆岩层完整程度、地面监测获得的变形数据,结合地下采空区情况及附近河流的水量变化、民房开裂现状等,量化分析了煤矿开采影响范围,提出了贵州山区煤矿开采影响移动角、导水裂隙带高度的确定方法以及疏排水范围与地下开采影响移动角的关系,并指出了相关工作中应注意的主要问题。
In this paper the impact of coal mining on the surface in the mountainous area of Guizhou is analyzed,using drilling,sonic logging,ground monitoring and other methods,according to the groundwater level exposed by the drilling project,the integrity of the overlying strata in the goaf identified by the sonic logging,and deformation data obtained by ground monitoring,combining with the situation of underground goaf and the change of water volume of nearby rivers,the current situation of civil houses cracking,etc.,the influence range of coal mining was quantitatively analyzed,and the method for determining the mining-influence moving angle and the height of water guiding fracture zone was proposed for coal mining in Guizhou mountainous areas,as well as the relationship between the drainage range and mining-influence moving angle,and finally,the main problems that should be paid attention to in related work were pointed out.
