一概述 双鸭山矿区位于黑龙江省东北部,是我国新兴的煤炭基地之一。现已开发的煤田东西长五十公里,南北宽五十公里,面积约二千五百平方公里。煤系地层为上侏罗纪,岩系属鸡西统,含煤地层总厚度为五百至三千米左右,计含可采煤层四至十五层,总厚度为三点二米至二十米,平均煤厚一点二米左右。总的来看,以薄和中厚煤层为主,但分布情况不一。其特点是,薄煤层多,中、厚煤层少;局部可采层多,全区发育的可采层少;中厚煤层的厚度在下限的多,薄煤层的
An Overview Shuangyashan mining area is located in the northeast of Heilongjiang Province, is one of China’s emerging coal bases. Coalfield has been developed fifty kilometers long east-west, north-south width of 50 kilometers, an area of about 2500 square kilometers. The coal-bearing strata are Upper Jurassic and the rock series are Jixi. The total thickness of the coal-bearing strata is about 500-3000 meters, including four to fifteen layers of mineable coal seams with a total thickness of 3.2-2.0 Meters, the average coal thickness of about 1.2 meters. In general, thin and medium thick seams are dominated, but the distribution is different. Its characteristics are: thin coal seam, medium and thick seam less; local recoverable layer, the development of the region less recoverable; medium and thick seam thickness in the lower limit of more than the thin seam
