3202工作面过断层破碎带加固技术实践

Practice on Reinforcement Technology of 3202 Working Face Passing Through Fault Fracture Zone

南阳煤业3202综放工作面过F12断层破碎带时面临顶板冒落、难控制等安全隐患,设计了超前加强支护等过断层破碎带的技术方案,过断层期间无漏顶、冒顶事故的发生,为企业创造了较好的经济和安全效益。

When 3202 fully mechanized top coal caving face of Nanyang Coal Industry passes through F12 fault fracture zone,it is faced with hidden danger of roof falling and difficult to control.The technical scheme of strengthening support in advance is designed to pass through fault fracture zone.There is no roof leakage and roof fall accident during the fault crossing,which creates good economic and safety benefits for the enterprise.
