坚硬顶板预裂爆破技术在综采工作面的应用

Application of Hard Roof Pre-cracking Blasting Technology in Fully Mechanized Mining Face

煤矿开采期间,工作面顶板区域一旦发生大面积垮落现象,容易发生瓦斯含量超标、顶板事故等各种事故。事故的发生不仅会影响煤矿开采作业的进行,造成巨大经济损失,而且可能会发生人员伤亡。为了保证煤矿开采顺利进行,减少事故的发生,针对综采工作面,应当加强对坚硬顶板预裂爆破技术应用的探讨。

During coal mining,once a large area of collapse occurs in the roof area of the working face,various accidents such as excessive gas content and roof accidents are prone to occur.The occurrence of accidents not only affects the progress of coal mining operations,causing huge economic losses,but may also result in casualties.In order to ensure the smooth progress of coal mining and reduce the occurrence of accidents,it is necessary to strengthen the exploration of the application of pre cracking blasting technology for hard roof panels in fully mechanized mining faces.
