5303综放面复合高分子综合防火技术

On the Composite Polymer Fire Protection Technology of Full Mechanized Caving Face

为降低矿井安撤成本,提高矿井效益,5303综放面停采后,工作面支架暂不回撤即进行临时封闭,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。

In order to decrease the cost of mine retreat, improve the efficiency of the mine, after 5303 fully- mechanized caving face stops mining, coal face support does not retreat to be temporarily closed, after5302 cutting- hole becomes systematic, it will be transferred to the new cutting hole. Temporary confinement time is long, and driving along the closed area can form a more open environment for air leakage. It is important to do a good job in 5303 fully caving mechanized face spontaneous combustion prevention and control work, since it is directly related to the mine safety production and the production task completion.
