Multi Factor Coupling High Static Load Narrow Short Working Face Anti Impact Management and Control Countermeasures
Rock burst is the key to disaster prevention and governance in Juye mining area.Pengzhuang Coal Mine is located in Juye mining area and belongs to a rock burst mine with a burial depth of over one kilometer.The impact risk of multi factor coupling high static load working face with large buried depth is high,and the difficulty of governance is great.According to the anti impavt technology route of"strong pressure relief,strong support,and strong monitoring",targeted anti impact measures such as high density and large diameter drilling for pressure relief,roof blasting pre cracking,and increasing passive support density are adopted in the 3307 working face of the mine.This effectively reduces the stress concentration degree of the triangular coal pillar in the goaf,and solved the problem of safe push mining in high static load narrow short working faces affected by multi factors such as large buried depth,goaf,roadway cutting,faults and so on.
