在探巷实测、取样分析的基础上,进行有限元数值模拟和相似材料模拟,研究条带采空区上近距离煤层上行开采的工作面底板稳定性。得出了可行的开采方法,并探讨了底板失稳的机理。
On the basis of the actual measurement and sampling analysis, the finite element numerical simulation and the simulation of similar materials are carried out to study the stability of the working face of the coal mining face in the goaf. The feasible mining method is obtained, and the mechanism of instability of floor is discussed.
