为解决堆存在郴州西河两岸近250万t的尾砂以及某矿区废弃的采空区所带来的地表与地下双重安全隐患，以堆存尾砂为充填骨料，使用尾砂胶结充填技术对采空区进行充填。该工艺不仅净化了地表环境，而且能够确保采矿作业的安全性，提高了矿山企业的经济效益与社会效益。实践证明利用地表堆存尾砂处理采空区技术上是可行的，经济上是合理的，应进行推广应用。

There piled nearly 2 .5 million ton of backfilling on both sides of West‐River and also some cavity was abandoned in a mine ,which caused double safety threat to both surface and underground .In order to deal with the double potential hazard ,we used the cemented tailings filling technology to fill the cavity , and the piled tailings were used as the filling aggregates .Not only can this technology purify the surface environment but also the safety of mining operations can be ensured ,which will improve both economic and social benefits of mining enterprises .Practice has proved that using stockpiling backfilling to dispose of cavity is technically feasible and economically reasonable thus popularization and application of the technology should be conducted .
