摘要
为了提高综采工作面破碎顶板稳定性,保证综采工作面安全高效回采,决定对8102工作面断层应力区破碎顶板采取水玻璃注浆技术进行加固。该技术提高了破碎顶板岩体稳定性及承载能力,保证了回采安全,取得了显著效果。
In order to improve the stability of broken roof in fully mechanized mining face and ensure safe and efficient mining in fully mechanized mining face,water glass grouting technology is adopted to reinforce broken roof in fault stress zone of 8102 working face.The technology improves the stability and bearing capacity of broken roof rock mass,guarantees mining safety and achieves remarkable results.
