试析煤矿回采工作面矿压与顶板管理

摘要

安全生产是煤矿开采工作的基本原则之一，但由于矿压作用，易引发一系列力学现象，造成围岩变形或工作面坍塌，影响回采工作安全、正常开展，而顶板控制作为安全回采的重要技术之一，却因管理不善衍生了诸多煤矿事故。在此，基于对煤矿回采工作面矿压影响的分析，结合顶板控制问题，就如何加以管理进行了探讨。%Safety production is one of the basic principle in the mining of collieries ,but because of mine pressure , a series of mechanical phenomenon will easily occur and lead to surrounding deformation or collapse face ,which influences on safety stoping .As one of the important technology of safety stoping ,roof controlling lead to many coal mine accidents because of its mismanagement .On the basis of analyzing mine pressure in working face ,the paper discusses how to manage it combined with the problems of roof controlling .
