自内蒙古自治区乌海市煤田“灭火工程”实施以来,已使7000多万吨煤炭资源得到有效保护,总体实施效果明显。近日,笔者从内蒙古自治区国土资源厅了解到,乌海市煤炭资源主要分布在乌达煤田和卓资山煤田,从上世纪60年代中期开始,乌达矿区煤层发生自燃,到了80年代,卓资山煤田也陆续出现煤层自燃发火现象,形成多处煤田火区。目前,两个煤田内的火区面积约达到848万平方米,并仍有向深处及周边蔓延的趋势。煤田自燃对乌海市大气环境质量和区域内的
Since the implementation of “Fire Extinguishing Engineering” in Wuhai Coalfield in Inner Mongolia Autonomous Region, over 70 million tons of coal resources have been effectively protected, and the overall implementation effect is obvious. Recently, I learned from Inner Mongolia Autonomous Region Department of Land and Resources, Wuhai coal resources are mainly distributed in the Wuda Coalfield and Zhuo Zhishan coalfield, from the mid-60s of last century, the coal spontaneous combustion occurred in the Wuda mining area, to the 80’s, Coal mines have also spontaneous combustion phenomenon has emerged, the formation of many coalfield fire area. At present, the fire area in the two coal fields has reached about 8.48 million square meters and there is still a tendency to spread to the depths and the surrounding areas. Spontaneous combustion of coal in Wuhai City, the atmospheric environmental quality and within the region
