兴文县新华硫铁矿地质环境恢复治理

矿山地质环境建设是目前国土资源生态建设的重点，选择四川省兴文县新华硫铁矿作为重点研究对象，在全面分析区域自然背景的基础上，提出主要存在的矿山地质灾害问题，包括水环境问题、大量耕地被破坏和占用、滑坡、崩塌、大气污染等。确定矿山地质环境恢复治理内容后，相应制定了多种治理方案，通过方案比选给出了推荐治理方案。推荐治理方案由采空区工程、地表排泄工程、矿渣拦挡工程、矿渣拦於工程、崩塌危岩处理工程、土地复垦工程和植被工程等组成。对预期的经济效益、社会效益和环境效益进行分析。最后为保证项目顺利实施，建议建立一套完善的保障措施，包括行政管理、技术监督、运行管理等，使地方社会经济可持续发展。

COUNTERMEASURE OF GEOLOGICAL ENVIRONMENT IN XINHUA MINING IN XINGWEN COUNTY OF SICHUAN PROVINCE

Geological environment construction is an emphasis of ecological construction in China.In this paper,Xinghua sulphur-iron mining in Xingwen County of Sichuan Province is selected as the study site.Many natural background parameters has been analyzed,including relief,geological,climate,hydrology,human activity,etc.Thus,the status and problems of geological disaster were discovered.The main problems of geological environment include the followings:(1) the water environment has been destroyed;(2) a large quantity of plowland has been destroyed or occupied by mining activities;(3) many geological hazards have been induced;and(4) atmosphere has been polluted.On the base of known technology and policy,the contents of geological environment construction have been made certain,and three projects have been established.After comparing with these projects,the authors present recommendatory projects including 7 parts of branch works.Due to this project,expectant benefits are analyzed,including economic benefit,social benefit and environment benefit.In order to ensure that the project can be successfully put in practice,some advices have been proposed.
