井田内地质构造简单，整个矿井区地层产状平缓，各主采煤层顶、底板岩层节理

The geological structure in the mine field is simple, the stratum of the whole mine area is gentle, and the joint fissures in the top and bottom rock layers of the main coal seams are moderately developed. When sandstone is the top and bottom plate, the stability is good. When the mudstone is the top and bottom plate, it is easy to crack in the horizontal direction due to weathering. The stability is poor. Pay attention to the occurrence of roof collapse during coal mining. <br>At present, there is no water hazard accident in the production process of the mine. The coal seam in the mine field is shallowly buried, and the main water damage is atmospheric precipitation infiltration replenishment, which infiltrates the aquifer above the coal roof through rock layer fissure infiltration. In the empty area or roadway, the underground influx is relatively large, which has a certain influence on coal seam mining.

The geological structure in the well field is simple, the formation of the whole mine area is flat, and the core coal seam top and bottom plate rock layer are medium-developed. When sandstone is the top and bottom plate, the stability is good, the mud rock is the top, the bottom plate is weathered and the horizontal direction is easy to crack, the stability is poor, in the process of coal mining should pay attention to the occurrence of roof collapse.<br>At present, there are no water hazardaccidents in the production process of the mine. The coal seam in the well field is shallow, the main water hazard is atmospheric precipitation infiltration recharge, through the rock layer crack infiltration recharge coal top plate above the aquifer, after coal seam mining, aquifer water through the crack, falling band crack, water tap belt seepage into the mining area or roadway, the underground surge volume is large, has a certain impact on coal seam mining.

The geological structure in the mine field is simple, the occurrence of strata in the whole mine area is gentle, and the joints and fissures of the roof and floor strata of the main coal seams are medium developed. When the sandstone is the top and bottom, the stability is good. When the mudstone is the top and bottom, it is easy to crack along the horizontal direction after weathering, and the stability is poor. In the process of mining, we should pay attention to the occurrence of roof caving.<br>At present, there is no water disaster in the process of production. The coal seam in the mine field is buried shallowly, and the main water hazard is supplied by the infiltration of atmospheric precipitation. The aquifer above the coal roof is supplied by the infiltration of the rock fracture. After the coal seam is mined, the aquifer water infiltrates into the goaf or roadway through the fracture, the caving zone fracture and the water conducting fracture zone. The underground water inflow is large, which has a certain impact on the coal seam mining.<br>
