利用卸压巷道技术控制深井回采巷道变形破坏
Theoretical and practical study on supporting of yielding roadway in deep mine
摘要
Abstract
The mining gateways in the deep mine are subjected to the surrounding rock pressure, the dynamic pressure of the coal mining face, and the movement of the main roof of the adjacent gobs beside the working face. The surrounding rocks occur with a serious deformation and destruction, a larger floor heave, and a difficult maintenance. This paper, building on the geological and earth pressure conditions of the mining gateways of left twelve working face at No. 5 mining area of Donghai coal mine, introduces the yielding roadway, and describes the mechanism by which the problem is removed, calculation of the location of the yielding roadway, the width of supporting coal pillar, yielding pillar and gateway. The study allows the yielding roadway to be used as the leaving gas roadway in coal mining face. The practice, as is the case with Donghai coal mine, shows that when used under certain conditions, the yielding roadway, a method working with better results, is capable of taming the deformation occurring in deeper roadways.关键词
