摘要
以12605综采工作面为研究对象,通过分析影响工作面回采具体因素,系统论述了沿空留巷回采作业整体施工过程,重点阐述沿空留巷支护方式。结果表明,运用此项技术不仅提高了资源回收率,而且极大节省了人力、物力资源,有效地解决了资源浪费、生产环节连贯等技术问题,同时还降低了开采过程中的安全事故,达到了预期目的。
Taking No.12605 fully mechanized mining face as the research object,through analyzing the specific factors affecting the mining of working face,the whole work process and support mode of gob-side entry retaining were discussed systematically. The practice shows that the use of this technology not only improves the recovery rate,greatly saves manpower and material resources,but also reduces the accident in mining process.
