摘要
煤矿顶板安全问题日趋严重,加强顶板灾害的预防和治理是未来煤矿安全工作的重点。项目通过对东滩煤矿1306轨顺围岩压力在线监测,研究初掘巷道迎头压力变化规律、岩石断裂时的声发射活动特征等重大技术难题,为掘进巷道支护提供技术支持。
The security problem of coal mine roof is increasingly severe. It is very important to strengthen prevention and management of roof disaster for future security work of coal mine. By online monitoring on surrounding rock pressure of 1306 tunnel in Dongtan coal mine, the pressure change law of initial excavation tunnel and Characteristics of acoustic emission of rock fracture have been researched. This will pro-vide technical assistance for Tunnel support.
