摘要
Abstract
By strata control observation and numerical simulation in the first shot firing and roof - coal working face with large inclined angle in Lugou coal mine of Zhengzhou coal industry Co. , Ltd. , it has been obtained that the supports resistance distributed in resist- ance - diminishing status during the mining process in shot firing and roof - coal working face with large inclined angle, the supporting pressure along the incline showed ＂saddle shape＂, and the peak of the supporting pressure of head entry is higher than air tail entry＇s. Therefore it＇s difficult for roadway to maintain.关键词
