摘要
针对平朔公司井工一矿9004工作面存在煤层厚度大、采空区遗煤多、采用均压通风、工作面设备多等问题,本文提出了工作面停采、工作面回撤以及采空区封闭后的主要防灭火技术措施。为了提高易燃厚煤层超长孤岛综放工作面在终采和回撤期间的防火安全,根据煤自然发火防治理论和孤岛综放工作面自燃特点,提出了全工作面支架壁后铺设风筒布堵漏防灭火技术,研究了快速回撤工艺,开发出快速装卸平台,从而大大增加了终采和回撤期间的安全性,为安全生产提供了保障。
For a mining company Pingshuo face 9004 with problems of in thick, Gobs more coal, the use of pressure ventilation and face many equipments raised face stopping, Face retracement And the main technical measures against fire after the gob is closed. In order to avoid the happening of the many problems to mine with all kinds of loss, it can be find many ways to salve those problems in the thesis. Through theoretical study and practical exploration, it achieves good results, and ensures the smooth face retracemently, and guidance to face the retracement Pressure Ventilation with reference. It accumulates valuable experience for the problem of Face Pressure to Withdraw caving and also it provides a way and experience to solve similar problems for other mines. Greatly improved the safety of the Past of the end of the period, and provides the guarantee for safe production.
