提高煤矿井下供电质量减少高瓦斯掘进头面的排放瓦斯次数

Improve Level of Supplying Electricity to Mine,Eliminate Discharging Times of Gas on Heavy-gas Filled Tunneling Working Surface

高瓦斯掘进头面瓦斯超限主要原因是局部通风机的停电、停风造成的排放瓦斯次数较多,因此从局部通风机供电的可靠性、安装、管理、双局扇自动投切、供电线路的检修等方面进行了表述,并就如何减少高瓦斯掘进头面瓦斯超限事故,从局部通风机的供电电源的可靠性入手,实现高、低压侧双电源、局扇"双三专",加强供、用电管理,规范供电系统的检修工作等提出了改进措施。

The high gas tunneling headdress gas ultra limits, mainly because the partial ventilator power cutring, out of blast creates the emissions gas number of rimes are many. Therefore, has carried on the indication rom the partial ventilator power supplying reliability, the installment, the management, the pair of partial fan threw automatically cuts, supply line aspects overhaul, and proposed the improvement measure on how to reducing the high gas tunneling headdress gas ultra to limit the accident, realizing high pressure, low pressure side double power source, bureau fan ＂pair three specially＂ from the partial ventilator electric power supplying reliable obtaining, the enhancement for, uses electricity the management, the standard power supply system overhaul work and so on.
