双阳矿现有两对生产井,设计能力150万t/a,1990年生产原煤165万t。全区共含煤43层。其中可采16层。厚度0.8～2.0m,最厚达4.2m。煤层倾角一般为10°～12°,煤层露头全部隐伏在18～60m厚的第四系冲积层下,且3/4在含水砂层下,上部又有七星河,水文地质条件较复杂。针对矿区地质构造、水文地质条件复杂等特点,因地制宣地改革采煤方法,提高资源回收率,为国家多出煤炭28.2万t,取得了较好的经济和社会效益。
Shuangyang existing two pairs of production wells, design capacity of 1.5 million t / a, 1.65 million tons of raw coal in 1990. The region a total of 43 layers of coal. Which can adopt 16 layers. Thickness of 0.8 ~ 2.0m, the maximum thickness of 4.2m. Coal seam dip angle is generally 10 ° ~ 12 °. Coal outcrops are all concealed under 18 ~ 60m thick Quaternary alluvium, and 3/4 are under the water-bearing sand layer. There is also Qixing River in the upper part, and the hydrogeological conditions are complicated. In view of the characteristics of the geological structure and the complex hydrogeological conditions in the mining area, the reform of coal mining methods to improve the resource recovery rate resulted in more coal output of 282,000 t for the country and achieved good economic and social benefits.
