摘要
通过对1138m分段道与分层联络道的变形监测,结合现场巷道破坏、工程地质条件、地应力环境、支护特性、采动影响等的调查研究,指出了采准巷道失稳的主要原因,并据此提出巷道支护时宜强不宜弱的观点和地压控制措施,为后续采矿的顺利进行提供了科学依据。
Through the deformation monitoring of 1138m2 sublevel drift and slice connections in combination with investigations in drifts damage, engineering geology conditions, ground stress environment, support performance and mining disturbance effect etc.,the author pointed out the main causes for the development drifts instability and advanced the views that drift support should be stronger rather than weak and ground pressure-controlled measures so as to provide scientific basis for smooth subsequent mining oper...
