一、概述我矿庞庄井现开采为石盒子系上、中层煤,属低沼气矿井,煤尘爆炸指数为38.98%,煤层自燃倾向等级为2～3类。自1980年使用奥地利 Am—50掘进机,至1982年10月共掘进巷道8056m。该机配备有除尘器,除尘器全长9.365m,宽1.160m,高1.430m,总重量为8.695t。除尘器所需风量300m~3/min,风机负压为1030mmH_2O,总功率为111kW(除尘器于1981年6月停用)。
I. Overview Mine Pangzhuang well mining for the Shihezi Department, the middle layer of coal, is a low-methane gas mine, coal dust explosion index was 38.98%, coal seam spontaneous tendency rank of 2 to 3 categories. Since 1980, the Austrian Am-50 roadheader was used. By October 1982, a total of 8056m of roadways had been excavated. The machine is equipped with a dust collector, dust collector length 9.365m, width 1.160m, height 1.430m, the total weight of 8.695t. The required air volume of the precipitator is 300m ~ 3 / min, the negative pressure of the fan is 1030mmH_2O, and the total power is 111kW (the precipitator was deactivated in June 1981).
