摘要
煤矿采空区场地因其地基稳定性差、承载能力低,不能被大范围用作建筑用地,这为工程建设带来诸多不便,采用有效的勘察手段对采空区进行前期勘察可以较大程度地避免此类问题的发生。本文采用"物探+钻探"方法对晋城某煤矿采空区场地进行勘察,并对采空区地基稳定性进行简要分析评价,最终确定采用注浆充填法对采空区地基进行加固治理,进而保证地基的稳定性,使其满足地基承载能力及抗变形限值的要求。
Due to poor foundation stability and low carrying capacity, the coal mined - out area cant be used as a large - scale construction site, which brings many inconveniences to the project construction. Pre - inves-tigation of the mined - out area by effective survey means can be largely avoided the occlems. In this paper ,te geoppysical prospecting ＋ drilling method was used to survey thecoalmine in Jincheng , and the stability of the foundation in the goaf was briefly analyzed andly,the grouting filling method is adopted to reinforce and control the founnation of goaf , and to ensure the sta-bility of the foundation , so that it can meet the requirement of bearing capacity and resisting deformation limit value.
