深井高应力高突区域回采巷道变形特征及控制
Deformation characteristics and controlling of tailgate in high stress high gas and outburst region of deep mine
摘要
Abstract
Concerning the intense distortion of surrounding rocks in Shoushan No.1 mine in excavation process, field investigation, coal and rock test, theoretical analysis, underground test and measurement were conducted. After analyzing deformation failure characteristics and support difficulties, the key technology of surrounding rock controlling of this type was proposed. Results indicated that rapid rate, serious floor heave, large accumulative amount are the main features of tailgate deformation. The system of high pre-stress and high strength bolt supporting, the technology of synchronous bearing of bolt and anchor, appropriate resisting and concession technology, reserved section technology, supporting and reinforcing technology of key parts are adopted to effectively control deformation. The industrial test showed that the roadway deformation of two sides was controlled within 180 mm, and roof within 170 mm, after support was provided. This proposed support technology can effectively control the surrounding rock deformation in deep roadway.关键词
