河北省丰宁县磐峰石料厂矿山地质环境问题及防治对策研究

Study on geological environment of mine in Panfeng Stone Plant, Fengning County, Hebei Province and its countermeasures

本文通过河北省丰宁县磐峰石料厂矿山生态地质环境调查,认为该区域地质环境问题主要为露天采坑、渣堆、高陡边坡等。对掌子面危岩、浮石进行清理以消除崩塌隐患,对开采边坡处的废渣进行放缓坡堆积、采坑回填,部分废渣堆坡脚修建干砌石挡墙然后进行绿化等,有效消除了矿山地质灾害隐患,保护了矿山地质环境,增加了绿化面积,恢复了其生态环境服务和利用功能。

Based on the investigation of eco-geological environment of Panfeng Stone Plant in Fengning County, Hebei Province, the paper considered that the main geological environment problems in this region are open pit, slag heap, high and steep slope, etc. The dangerous rock and pumice stone on the face of the palm need to be cleaned for decreasing the hidden danger of collapse. The waste slag on the mining slope need to be piled up gently and backfilled. Part of the waste slag piled at the foot of the slope could be used in building a dry stone retaining wall and then greening, etc. Those countermeasures can effectively eliminate the hidden danger of geological disasters in the mine, protect the geological environment of the mine, increase the green area, and restore its ecological environment service and utilization function.
