摘要
矿山在开采过程中,受到采动影响和地应力的改变,往往在地表引起不同规模的地裂缝。开采方通常对于这些地裂缝的具体展布和贯通性不是很明确,给矿方下部煤层的安全开采造成极大困扰。本文对以往地质、水文资料的分析基础上,采用地质雷达对内蒙古某煤矿的探测,初步分析地裂缝的成因,了解工区内浅部裂缝空间展布特征及规律;为后续钻探等工程手段提供地球物理依据。
In the process of mining,the influence of mining and the change of ground stress often cause ground fractures of different scales on the surface.The mining party is usually not very clear about the specific distribution and penetration of these ground fractures,which causes great trouble to the safe mining of the coal seam below the mining party.Based on the analysis of previous geological and hydrological data,this paper uses geological radar to detect a coal mine in Inner Mongolia,preliminarily analyzes the causes of ground fractures,and understands the spatial distribution characteristics and rules of shallow fractures in the working area.It provides geophysical basis for subsequent drilling and other engineering means.
