综放初采顶板气相压裂技术应用

Application of Gas Fracturing Technology during Initial Mining on Fully Mechanized Face

综放工作面在初采前进行顶板预裂是安全生产中一项非常重要的工作。顶板爆破预裂安全性低、操作复杂,顶板气相压裂技术不会产生有害气体和引起瓦斯爆炸事故,安全性高。通过实例验证了气相压裂技术在综放工作面顶板预裂中的可行性。

For roof pre - fracturing is a very important work of production safety before the initial mining in fully - mechanized face. The security of roof pre - fracturing blasting is low and complicated to operate, roof gas fracturing technology does not produce harmful gases and cause gas explosion, and with high safety. It is showed through a concrete instance that the gas fracturing technology is feasible on the roof pre - fracturing of fully mechanized caving face.
