摘要
Abstract
In order to evaluate the protective effect of Mengjin Coal Mine in Xin'an Coal Field after the first use of protective layer mining on the protected layer,through methods such as on-site measurement,laboratory testing,numerical simulation and so on,a comprehensive analysis is conducted on the residual gas content,residual gas pressure,permeability coefficient,maximum expansion deformation amount,pressure relief angle along the inclined direction and trend,and protection range of the protected layer after protective layer mining.Through the observation of gas emission quantity in the working face of the protected layer during actual mining,it is verified that the first application of protective layer mining in Xin'an Coal Field achieves good effects,realizes a major breakthrough in the application of protective layer mining in Xin'an Coal Field.关键词
