摘要
杨村煤矿330工作面属于厚松散层薄基岩工作面,桲椤树二号正断层贯穿整个工作面,断层附近突水溃砂风险较大。通过对断层超前预注浆加固,提高断层破碎带的整体性和稳定性,减小因断层影响的冒裂带发育高度,从而实现工作面安全开采。
The 330 working face of Yangcun Coal Mine belongs to the working face with thick loose layer and thin bedrock.The No.2 normal fault of Poluoshu runs through the whole working face,and the risk of water and sand burst near the fault is high.Through the pre grouting reinforcement of the fault,the integrity and stability of the fault fracture zone are improved,and the development height of the fracture zone affected by the fault is reduced,so as to realize the safe mining of the working face.
