Research on Prevention and Control Engineering of Burst Rock Pressure in Subsection Mining of Steeply Inclined Coal Seam
In response to the problem of mining pressure impact during segmented mining of steeply inclined coal seams in a certain coal mine,this paper studies and analyzes the collapse characteristics of the overlying rock during segmented mining,the impact mechanism of segmented mining,and proposes a plan to prevent mining pressure disasters by using pressure relief prevention and control technology for dynamic and static load sources.Dynamic load prevention and control are achieved through deep hole blasting of the coal seam roof,and static load prevention and control are achieved through drilling and blasting of the bottom plate.The implementation of the mine pressure prevention and control plan in a certain working face showed that after implementing the mine pressure prevention and control measures,the number of mine tremors and total energy during mining operations gradually decreased,and the mine pressure prevention and control effect was good.
