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