黑龙江砂宝斯金矿环境工程地质问题研究

目前，砂宝斯金矿区已进入矿山建设与开发阶段，矿区开采必然会引发一系列工程地质和环境地质问题。矿区断裂较发育，地表风化强烈，风化裂隙发育，工程地质环境质量属于较差-中等，边坡及地下采空区围岩的稳定性是主要的工程地质问题。区内地表水水质较好，但地下水水质较差，砷、铁、锰及耗氧量普遍超标；矿区土壤受原生环境的影响，砷含量较高。通过预测该区潜在的环境工程地质问题，提出了相应的防治措施，以期为后续的矿山建设与开发提供依据。

Study on the Problems of Environmental Engineering Geology in Shabaosi Gold Deposit,Heilongjiang Province

Currently,Shabaosi gold deposit has entered the stage of construction and exploitation,which will inevitably cause a series of problems of engineering and environmental geology.The fault well develop,the surface weathering strong and crack grow,engineering geology environmental quality is poor-moderate in the region.The stability of surrounding rock in slope and underground mined-out area are the main engineering geological problems.Surface water quality is good,ground water quality is poor in which arsenic,iron,manganese,oxygen consumption generally exceeded.The soil has a high content of arsenic which caused by the native environment.We predict the possible environmental engineering geological problems and propose corresponding prevention recommendations to provide the basis for construction and development of the mine.
