摘要
针对霍州煤电集团的团柏矿井11-101回采工作面,从煤巷支护条件、巷道尺寸、支护形式和支护参数校核等方面研究大水条件下近距离煤巷支护技术。该技术采用高强、高预紧力锚杆进行支护,实现了围岩的主动支护,提高了围岩的强度及整体性,保证了巷道安全,实现了此种条件下工作面的安全生产。
This paper analyzes the mine water close coal roadway supporting technology of Tuanbai Coal Mine from supporting conditions, supporting froms and size of roadway of 11-101 working face, with high strength and high pre-tightening force of anchor supporting, it realizes the active support of surrounding rock, enhances the strength and integrity of surrounding rock s, and ensures the safety of roadway, at last, it also realizes the working face under the condition of safety production.
