矿山地质分布特征情况及勘查研究

Characteristics of Mine Geological Distribution and Exploration

为我国矿山开采环境问题得到解决,资源得到有效利用,提出矿山地质分布特征情况及勘查研究。通过分析平原盆地,戈壁沙漠以及黄土高原三个环境区地质分布特征,发现平原盆地环境区内海水侵蚀地下,地下水位下降,土地盐碱化严重;戈壁沙漠环境区生态环境脆弱,土地沙化植被退化情况严重;黄土高原环境区内水环境破坏和地面塌陷情况严重。通过遥感技术勘测矿区风化情况,明确矿山资源分布规律,提取围岩蚀变信息,完成矿山地质勘查方案。以柳湾煤矿为例展开勘查研究,发现其土地压占、排矸场压占、露天开采压占分别占了47.29公顷、317.09公顷和580.87公顷,其中露天开采压占最为严重。为解决矿山开采环境问题提供基础资料。

To solve the problems of mining environment and utilize resources,the geological distribution characteristics and exploration are proposed.By analyzing the geological distribution characteristics of the Plain Basin,Gobi Desert and Loess Plateau,the ecological environment,the Gobi desert is fragile,the land desertification vegetation degradation,and the water environment damage and subsidence in the Loess Plateau.Survey the mine weathering by remote sensing technology,clarify the distribution law of mine resources,extract the information of surrounding rock erosion,and complete the mine site Quality survey scheme.Taking Liuwan coal mine as an example,it is found that the land pressure,gangue yard pressure and open-pit mining pressure account for 47.29 hectares,317.09 hectares and 580.87 hectares respectively,of which the open-pit mining pressure is the most serious.To provide basic data for solving environmental problems in mining.
