摘要
石煤是一种分布广泛的能源资源,但因其中含有一定量的钒、铬、锰、硫等重金属元素和有毒有害元素,通过渗滤液,重金属元素和有毒有害元素溶解于水中,流入溪水或渗入地下后,对水、土环境造成污染,严重影响到水、土环境安全。作为燃料燃烧后所产生的烟雾、粉尘具有一定的毒性,对大气环境产生污染。同时,因含硫较高,也易产生自燃,进而污染水、土、大气环境。在石煤矿山开发过程中,易产生开采面边坡崩塌、滑坡地质灾害。本文通过对石煤矿山渗滤液水质成份、渗透途迳、自燃影响因素等分析,指出水环境、土壤环境、大气环境污染和地质灾害产生特征,提出防治措施建议,为石煤资源的合理、有效开发利用提供参考。
Stone coal is a widely distributed energy resource,but it contains a certain amount of heavy metal elements such as vanadium,chromium,manganese,sulfur and toxic and harmful elements.Through leachate,heavy metal elements and toxic and harmful elements dissolve in water,flow into streams or seep into the ground,causing pollution to the water and soil environment,which seriously affects the safety of the water and soil environment.Smoke and dust produced after combustion as fuel have certain toxicity and pollute the atmospheric environment.At the same time,due to the high sulfur content,it is also prone to spontaneous combustion,which in turn pollutes the water,soil and atmospheric environment.In the development of stone coal mines,geological disasters such as slope collapse and landslide are easy to occur.Based on the analysis of the water quality composition,infiltration path and spontaneous combustion influencing factors of leachate from stone coal mine,this paper points out the characteristics of water environment,soil environment,atmospheric environmental pollution and geological disasters,and puts forward some suggestions on prevention and control measures,so as to provide reference for the rational and effective development and utilization of stone coal resources.
