海南某铁矿露天采场挂帮矿(以下简称挂帮矿)随着采矿工作的持续进行,回采区及其地表(项目部所在地、项目部至挂帮矿的公路沿线和挂帮矿36米中段硐口附近)的环境地质条件不断恶化.其中,项目部至挂帮矿的公路的一段边坡已发生了较大规模垮塌,使其已永久不能再使用.随着回采区不断向地表发展,对露天采场挂帮矿回采区及其地表环境地质条件有进一步恶化的趋势,具体情况如下.%As mining continuing, the environmental geology conditions become deteriorating in the area of mining recovery area and its surface of hanging wall ore ( hereinafter referred to as hanging wall ore ) in one iron mine open pit of Hainan. The specific environmental worsening area covered the location of project department, along the highway from the department to handing wall ore and near its cave mouth of the middle section in 36 meter, of which the slope of the section of the highway has collapsed on a large scale with the result that it cannot be used forever. With the continuous development of the mining area to the surface, the environment geology conditions of the study area show a trend toward further deterioration, and the specific conditions will be stated in this paper.
