Study of the response characteristics of the water–force coupling action of hard coal bodies in steeply inclined coal seams
Study of the pre-blast weakening of hard-top coal water injection is especially important to solve problems related to the low recovery rate of coal resources and frequent dynamic disasters due to the low degree of fragmentation of hard-top coal during high-stage fully mechanized top-coal caving in...
