综放面复合高分子综合防火技术研究

Research on Comprehensive Fire Orevention technology of Composite Polymer on Fully Mechanized Caving Face

为降低矿井安撤成本,提高矿井效益,鲍店煤矿5303综放面停采后,工作面支架暂不回撤进行临时封闭,待5302切眼形成系统后从5303面转支架至新切眼。工作面临时封闭时间长,沿空掘进对封闭区域形成较为畅通的漏风环境,做好5303综放面的自然发火防治工作,直接关系到矿井的安全生产及生产任务完成情况。

In order to reduce the mine install cost,and improve the efficiency of mine, while NO.5303 fully mechanized caving face of Baodian coal mine is stopped, face support temporarily withdraw temporarily closed until the cut of NO.5302 forming system from 5303 sides to support to the new working face cut eye. The working face is confronted with a long closed time, the gob side entry will form a relatively smooth leakage environment for the closed area. The prevention and control of spontaneous combustion on the NO.5303 fully mechanized top coal caving face is directly related to the safety production and the completion of production tasks.
