综采工作面破碎顶板安全维护措施研究
|
摘要
为了防止综采工作面顶板破碎出现顶板垮落事故,保证工作面安全高效回采,大同煤矿集团云冈矿技术科通过技术研究,决定对12#层81103工作面破碎顶板采取"注浆+超前撞楔支护+支架搭梁"等联合维护措施,实际应用效果表明,有效提高了破碎顶板稳定性,取得了显著成效。
In order to prevent roof collapse accident caused by roof breakage in fully mechanized mining face, ensure working face safe and efficient mining, the engineering department of Yungang Coal Mine, Datong Coal Mine Group made the technical research, decided to adopt "advance grouting + bump wedge supporting + stent by beam", the joint safeguard measures, for the 12# layer broken roof of 81103 face, and practical application effect shows that it effectively improve the broken roof stability, and has made remarkable achievements.
