河南省祁雨沟公峪矿区地质环境问题及防治措施

胶结尾砂充填法广泛应用于金矿的地下开采，不仅有利于矿产资源、围岩和尾矿的合理化开发与利用，而且可以最大限度地减小采矿活动对矿山地质环境的污染和破坏。以全胶结或胶结+尾砂的充填法在祁雨沟公峪金矿为例，通过野外实地调查和综合研究认为，现状地质环境问题为地面塌陷、地形地貌景观的破坏和地表土地的占压和破坏等；潜在地质环境问题为滑坡、泥石流和地面塌陷的发生，地形地貌景观破坏以及土地损毁的进一步加剧；并从预防和治理的角度，提出了对应的防治措施，以期为胶结尾砂充填法地下开采金矿提供生产、修复和保护的理论依据。

Geological environment problems and prevention measures in Qiyugou Gongyu Mining Area of Henan Province

Cement tailings filling method is widely used in underground mining of gold mine,which is not only conducive to the rational development and utilization of mineral resources,surrounding rocks and tailings,but also can minimize the pollution and damage of mining activities to the mine geological environment.Taking the filling method of full cementation or cementation+tailings in Gongyu Gold Mine of Qiyugou as an example,through field investigation and comprehensive research,it was believed that the current geological environment problems were ground collapse,destruction of landform and landscape,occupation and destruction of surface land,etc;The potential geological environment problems were the occurrence of landslide,debris flow and ground collapse,the destruction of landform and landscape,and the further aggravation of land damage;From the perspective of prevention and treatment,the corresponding prevention and control measures were proposed in order to provide a theoretical basis for production,repair and protection of underground gold mining with cement tailings filling method.
