基本概况 山东省煤炭资源丰富,品种齐全。全省含煤面积约16500平方公里,占全省国土面积的11.5％,-2000米以下浅煤炭总储量约700亿吨,居华东地区第二位。到1999年底,累计探明煤炭储量244亿吨,其中保有储量224亿吨。除已探明的储量外,尚有预测含煤区56处,面积10000平方公里,预测储量405.2亿吨。煤炭品种以气肥煤为主,并有焦煤、瘦煤、贫煤、褐煤和无烟煤等品种。 主要职业病的危害 煤炭行业是职业病危害的重点行业,存在一些特殊的职业安全卫生问题。煤矿主要以井下开采为主,地下作业终日不见阳光,潮湿、空气不流通;采矿中产生的大量粉尘,尤其是含有大量游离二氧化硅的粉尘等,对人体危害较大。同时,在煤炭采掘过程中伴有有害
Basic profile Shandong Province is rich in coal resources and has a good variety. The province’s coal-bearing area is about 16,500 square kilometers, accounting for 11.5% of the province’s total land area. The total reserves of light coal below 2,000 meters are about 70 billion tons, ranking the second in eastern China. By the end of 1999, a total of 24.4 billion tons of proved coal reserves had been accumulated, of which 22.4 billion tons were reserved. In addition to the proven reserves, there are 56 coal-bearing areas forecasted with an area of 10,000 square kilometers and a predicted reserve of 40.52 billion tons. Coal varieties to gas and coal-based, and coking coal, lean coal, lean coal, lignite and anthracite and other varieties. The harm of major occupational diseases The coal industry is the key industry of occupational disease hazards, and there are some special occupational safety and health problems. Mine mainly underground mining, underground operations all day long no sun, moisture, air is not circulated; mining generated large amounts of dust, especially containing a lot of free silica dust, etc., on the human body more harmful. At the same time, there is harmfulness in the coal mining process
