复杂构造应力采区沿空掘巷非对称支护研究
Asymmetric supporting research of gob-side entry driving in complex tectonic stress mining area
摘要
Abstract
When the working face is in the complex tectonic stress area,in order to determine the area ground stress condition,the method of stress relief is used to determine the region of high stress mainly constituted by tectonic stress. Based on the in-situ stress test results,the stress intensity and direction are used to load the initial ground stress in the numerical calculation model, which effectively reduces the error of the simulation results without considering the tectonic stress.Combined with evolution me-chanism of deformation and stress along the empty roadway, asymmetric supporting parameters has been designed.Using special anchor fastening shoulder artifacts effectively can reduce the chances of fracture anchor cables and improve the quality of the anchor cable bearing quality.The results of the industrial test and the rock pressure indicates that the asymmetric support scheme supporting effect is good in the complex tectonic stress mining area and has a remarkable economic and social benefit.关键词
