| Abstract: | Based on discussion about the features of karst groundwater resources distribution of karst water system in Heilongdong Springs and causes of spring groups cutoff and according to current karst groundwater resources and exploitation distribution conditions of coal resources, this paper put forward the measures for protecting groundwater resources, i.e. intensifying plugging of underground coal mine gushing water points, grouting in advance to reinforce the small faults and weak lower confining bed of coal seam and leave sufficient waterproof coal pillars based on adjustment of the water sources for centralized water supply and water supplying and draining and countermeasures of improving use ratio of mine water and replacement of direct exploitation to realize resuming flow of spring groups and sustainable development of groundwater resources and exploitation of coal resources |
