工作面煤与瓦斯突出危险性的模糊综合评判

针对煤与瓦斯突出是多因素共同作用的地质动力现象,以平顶山矿区5个突出工作面为例,在煤与瓦斯突出相关因素分析基础上,用模糊数学的方法对影响煤与瓦斯突出的多种因素进行了综合评判。划分出了不同的突出危险性等级,为突出分级管理提供了科学依据。     

Numerical Analysis on Displacement Law of Discontinuous Rock Mass in Broken Rock Zone for Deep Roadways

On the basis of the characteristics of broken rock zone, using the program of "discontinuous deformation analysis(DDA)", the changing law of influential factors of discontinuous rock mass in large broken rock zone was researched quantitatively for the first time. Based on the results of computation, the concept of "key part"of roadways and its stability criterion were brought forward, and it was pointed out that in inclined coal and rock seams the"key parts"of roadways are the upper side and the floor of surrounding rocks, especially the former.
