Characteristics of strong mine pressure manifestation in composite hard roofs and determination of main controlling layers
The interactions within the composite hard roof structure above coal seams are highly complex, making it challenging to identify the main controlling layers for pressure relief via hydraulic fracturing. Using the 31104-1 working face of the Nalinhe No. 2 Mine at Wushenqi Mengda Mining Co., Ltd. as t...
