矿山地质灾害勘查及其防治措施研究

Research on mine geological hazard exploration and its prevention and control measures

为了研究项目区内采空区的分布范围、影响程度以及现状,采用物探勘查推断采空区位置,结合钻探工作验证物探勘查成果的正确性,推断拟建项目区所在区域的地质灾害类型为采空区及上部岩层变化引起地面塌陷及地裂缝。基于此,提出了项目建设相关防治措施,主要包括地面沉降监测、注浆治理、建筑物的安全技术以及禁采措施。研究为勘查区地质灾害危险性评估和拟建建筑物的地基稳定以及人民生命和财产安全提供技术依据。

In order to investigate and study the distribution range,influence degree and current situation of the goaf,this article uses geophysical exploration to infer the location of goaf,and verifies the correctness of geophysical exploration results through drilling work.It is inferred that the geological hazards in the area where the proposed project area is located are ground subsidence and ground fissures caused by changes in goaf and upper rock layers.Based on this,relevant prevention and control measures are proposed,mainly including land subsidence monitoring,grouting treatment,building safety technology and mining prohibition measures.The research provides a technical basis for the risk assessment of geological disasters in the exploration area,the stability of the proposed residential buildings,and the safety of people′s lives and properties.
