老采空区地基稳定性附加应力-概率积分法评价

提出运用附加应力-概率积分法对半无限开采缓倾斜煤层的老采空区地基稳定性进行综合评价，为老采空区工程建设提供科学依据。以石家庄钢铁公司拟建原料基地为例，运用该方法分析了煤矿老采空区对工程建设的影响。分析认为拟建工程荷载不会使煤矿老采空区活化，采空区残余变形对拟建工程的影响在允许范围以内，对工程建设影响不大，在拟建场地进行工程建设基本可行，为采空区上方兴建工程提供了科学依据。

Foundation Stability Evaluation of Old Goaf Based on Additional Stress and Probability Integration

A new method that adopts additional stress and probability integration to reasonably evaluate foundation stability is applied to provide a scientific basis for the engineering construction of old goaf.Taking the material base to be built by Shijiazhuang Iron and Steel Company for example, the method is adopted to analyze the impact of engineering construction of old goaf, and the conclusion is that the load of building does not make old coal goaf awake.The residual deformation of old goaf is within the allowable range and almost does not affect to engineering construction.It is basically feasible to construct project above the old goaf, and the evaluation provides a scientific basis to build projects over the goaf.
