徐州矿务集团有限公司权台煤矿东井主、副井提升系统为混和立井,井筒内淋水比较大,冬季空气温度下降,井筒内壁、井道钢梁、电缆和罐道结存大量冰块。当空气温度上升时,结冰融化,冰块掉落。影响副提人员上、下井安全和井筒装备安全运行以及井筒装备的检修。井口智能热风机控制装置主要由可编程控制器PLC、软件程序、JWC温控传感器、电动闸阀何控制继电器等部分组成。热风机智能控制原理见图1。当
Xuzhou Mines Group Co., Ltd. Datong Coal Mine Dongjing main and auxiliary shaft hoisting system for the mixing shaft, well water inside the borehole is relatively large, the winter air temperature drops, borehole wall, hoistway steel beams, cables and a large number of ice storage tank. When the air temperature rises, the icing melts and the ice drops. Affect the safety of secondary escorts and the safety of well shafts and maintenance of wellbore equipment. Wellhead intelligent air blower control device mainly consists of programmable logic controller PLC, software program, JWC temperature sensor, electric gate valve control relay and other components. Air blower intelligent control principle shown in Figure 1. when
