江苏省太湖煤炭工业公司任墅煤矿,其井田第四系冲积层内有含水砂层及砾石层,其中砾石层蓄水性强,并直接与煤系地层接触,对矿井开采造成严重胁胁。为查明矿井水文地质条件;复岩破坏移动特征和两带高度;合理确定回采上限与浅部煤层的开采方案,实现水体下安全采煤,经太湖煤炭工业公司与我院订立协议,将任墅煤矿砾石含水层下的开采作为研究课题,开展科研工作,并被列入80—81年度江苏省煤炭科研的基本项目之一。
Renshu Coal Mine, Taihu Coal Industry Company, Jiangsu Province, has aquiferous sand and gravel layers in Quaternary alluvium of its minefield, of which the gravel layer is highly water-bearing and directly contacts coal-bearing strata, posing a serious threat to mine exploitation. In order to ascertain the mine hydrogeological conditions; the complex rock to destroy the moving features and the height of the two belts; reasonably determine the upper limit of mining and shallow coal seam mining program to achieve safe water mining, the Taihu Coal Industry Company and our hospital to make an agreement Mining under the gravel aquifer As a research project, it has carried out scientific research and was included in one of the basic projects of coal science research in Jiangsu Province in 1980-81.
