摘要
煤是我国主要能源之一,煤炭开采会带来环境污染和安全等一系列的问题,其中之一就是有害气体,它包括CO、CO2、CH4、H2S、NO2、SO2等,通常存在于通风不良的旧巷、采空区和火区附近以及在炮烟、沼气和煤尘爆炸时的风流中,这些气体浓度达到特定值,就会对人体产生损害,有的还会爆炸危及工人和矿井安全;通过分析煤矿井下常见的有毒有害气体基本性质及危害,提出了相应的预防措施。
Coal is one of Chinag primary energies, but coal mining has bought a series of problems such as environmental pollution, security, one of which is noxious gases, including CO, CO2, CH4, H2S, NO2, SO2 and so on, they are commonly found in poorly ventilated old roadway, goaf and in the vicinity of the fire area and in the airflow of artillery smoke, methane and coal dust during the explosion. These gas densities surpass certain values, it will harm the human body, sometimes will lead to explosion which can endanger workers＇lives and mine security. This article through analyzing the basic nature and harmness of the common noxious gases in the coal mine, proposes the corresponding preventive measures.
