| 摘 要： | 在分析神东矿区旺采采空区失稳危险18种影响因素的基础上,采用指数分析法对旺采采空区失稳危险进行了分级方法研究,建立了神东矿区旺采采空区失稳危险分级指标,确定了旺采采空区失稳危险指数W。将神东矿区旺采采空区失稳危险分级划分为5级,即Ⅰ级危险(特大危险性W≥0.80);Ⅱ级危险(重大危险性0.70≤W<0.80);Ⅲ级危险(较大危险性0.60≤W<0.70);Ⅳ级危险(一般危险性0.50≤W<0.60)和Ⅴ级危险(较小危险或无危险:W<0.50)。结合实例,对榆家梁煤矿52108旺采采空区失稳危险性进行了分级。实践表明,该分级方法是合理和可行的。

| Abstract: | On the basis of analyzing 18 influence factors of Wongawilli gob unstability danger,Wongawilli gob unstability danger index W was present by index analysis method.5 danger degrees of Wongawilli gob unstability were classed,that is,Ⅰ(super danger,W≥0.80),Ⅱ(great danger,0.70≤W<0.80);Ⅲ(major danger,0.60≤W<0.70),Ⅳ(common danger,0.50≤W<0.60) and Ⅴ(minor danger,W<0.50).Danger degree of 52108 Wongawilli gob in Yujialiang Colliery was classed.Practice showed the result was rational and feasible. |
