随着我国地质事业的迅速发展,解放以来通过大量勘察工作已掌握累积了丰富的水文地质资料。我国受水害威胁的煤炭资源约占探明储量的27%,据不完全统计,仅北方受底板岩溶水威胁的煤炭资源约200×108t。水文地质问题严重制约着北方煤炭资源可持续发展。
With the rapid development of geology in our country, a great deal of investigation work has accumulated a great deal of accumulated hydrological data since liberation. Coal resources threatened by water hazards account for about 27% of proven reserves in China. According to incomplete statistics, only the northern coal resources threatened by floor karst water are about 200 × 108t. Hydrogeology problems seriously restrict the sustainable development of coal resources in North China.
