Research on geological environment problems and restoration management of Mudangou Coal Mine
The coal-bearing strata in the mining area are mainly Jurassic,and there are two mining pits formed by mining,which are ex-cavated in a stepped shape.At present,the micro-geomorphology of"scarp-platform-scarp-platform-scarp"is formed.Among them,there are 17 slopes(divided into Q1-Q17 slopes)and 2 platforms(P1,P2),with accumulated water at the bottom of the mining pit.The main geological environment problems in the mining area are the damage to the terrain,landscape,and vegetation during coal mining,as well as the damage to land resources caused by mining pits.The mining area carried out geological environment management,with a manage-ment area of 277 646.6 m2,including 55 001.7 m2 for the first mining pit and 222 644.9 m2 for the second mining pit.In this manage-ment,slope dressing of Q1、Q3、Q10、Q11 and Q14 was carried out,and dangerous rock cleaning work was carried out on slopes of Q2、Q4-Q9.Among them,slope dressing work was carried out on slopes of Q15 and Q16,while slope dressing work was not done on slopes of Q12 and Q13 due to geological limitations.Leveling and planting grass for P1 and P2 mining platforms were carried out.In order to ensure the effectiveness of vegetation restoration,management and protection projects were implemented to ensure the survival rate of vegetation.Better social and environmental benefits can be obtained through the restoration and management of mine geological environment.
