| 摘 要： | 界沟煤矿位于淮北煤田南部，设计生产能力为0．6Mt／a，新构造活动不强，构造稳定性较好。通过对界沟煤矿环境地质现状监测和调查，认为目前环境现状质量良好；对煤层开采后引起的地面沉降与塌陷、矿井污、废水排放，固体废弃物，空气污染、噪声等对环境地质的影响进行了预测评价，预测地面沉降为12．0m，塌陷积水面积为9．25m^2，受影响的耕地为1316m^2，综合评价环境地质条件为不良即Ⅲ类；提出了采用煤矸石发电，对塌陷区回填复垦．对矿井排水进行处理和综合利用等环境地质保护的方法与措施。

| Abstract: | The Jiegou coalmine is situated at southern Huaibei coalfield, designed capacity is 0.6Mt/a, neotectonic motion is not strong and has rather good structural stability. Through environmental geological status monitoring and investigation in Jiegou coalmine, considered that the environmental quality status quo is good. Predicted and evaluated mining induced surface subsidences and collapses, sewage and waste water drainage, solid rejectamenta, air pollution and noise are all impact to environmental geological condition. Predicted surface subsidence is 12.0m, subsided ponding area 9.25m^2, as affected arable land 1316m^2, comprehensively assessed environmental geological condition is out of condition or category III. Put forward methods and measures to protect environmental geological condition such as waste power generating, subsidence area backfilling and reclamation, mine drainage water processing and comprehensive utilization etc. |
