我国是世界上厚煤层储量最大的国家之一,在全国统配煤矿中,厚度在3.5m以上的煤层约占总储量的43%。以大同煤矿集团公司(以下简称同煤集团)为例,随着采煤技术的不断发展,开采厚度5m以上的煤层将成为同煤集团若干年的主采煤层,为了适应这种需要,同煤集团拟兴建6个千万吨级矿井。
China is one of the countries with the largest reserves of thick coal in the world. In the coal mines nationwide, coal seams above 3.5m in thickness account for about 43% of the total reserves. Taking Datong Coal Mine Group (hereinafter referred to as Datong Coal Group) as an example, with the continuous development of coal mining technology, the mining of coal seams over 5m in thickness will become the main coal seam for several years with Tongmei Group. To meet this need, Coal Group intends to build six 10-million-ton mine.
