基于注浆充填技术的村庄下煤炭资源开采

村庄下压煤量为中国建筑物下压煤的大部分,为合理开发、利用煤炭资源,减少资源损失量,提高煤炭资源回收率,确保中国能源安全,通过对地表移动基本规律、开采覆岩破坏机理、建筑物采动损害与评估的研究,选择切实可行的采煤技术。通过现场工业试验表明,运用注浆充填技术取得很好的技术经济效果,具有很好的应用价值。

Research of coal mining under villages based on grouting filling technology

The amount of coal under village comprises most of coal under buildings in China.In order to develop and utilize coal resource effectively and reduce the loss amount,improve the recovery rate of coal resources,provide the practical and feasible coal mining technology through studying the surface movement basic rule,exploitation of overburden rock failure mechanism,mining damage and evaluation.the industrial tests show that the use of grouting and technology has made great technical and economic benefits,it is an worthy subject for further research.
