Implementation of clean mining technology at coal mines is crucial to protect the environment and maintain balance among energy resources, consumption, and ecology. After reviewing present coal clean mining technology, we introduce the technology principles and technological process of paste backfill mining in coal mines and discuss the components and features of backfill materials, the constitution of the backfill system, and the backfill process. Specific implementation of this technology and its application are analyzed for paste backfill mining in Daizhuang Coal Mine; a practical implementation shows that paste backfill mining can improve the safety and excavation rate of coal mining, which can effectively resolve surface subsidence problems caused by underground mining activities, by utilizing solid waste such as coal gangues as a resource. Therefore, paste backfill mining is an effective clean coal mining technology, which has widespread application.
煤矿实施清洁开采技术对于保护环境以及维持能源资源、消费和生态之间的平衡至关重要。在回顾了当前的煤炭清洁开采技术后，我们介绍了煤矿膏体充填开采的技术原理和工艺流程，并讨论了充填材料的组成和特性、充填系统的构成以及充填过程。针对岱庄煤矿膏体充填开采，分析了该技术的具体实施情况及其应用；实际实施表明，膏体充填开采可以提高煤矿开采的安全性和掘进率，通过将煤矸石等固体废弃物作为资源加以利用，能够有效解决地下开采活动引起的地表沉陷问题。因此，膏体充填开采是一种有效的煤炭清洁开采技术，具有广泛的应用前景。
