枣庄矿务局太原群各煤层都属于含硫量2.5%以上的高硫煤层。含硫成份中,硫化铁硫占60%,有机硫占40%。 正在开采的五个高硫煤层中,14层煤夹矸以硫化铁为主,呈结核状非连续分布,硫化铁最小块度50毫米,最大300毫米,一般在100毫米左右;16层煤的硫化铁以少量星点状、片状存在;17层和18层以星点状存在。 高硫煤层均为厚度1.3米以下的薄煤层,采用走向长壁式方法开采。过去虽采用过滚筒采煤机组、刨煤机和攉煤机等设备,
Zaozhuang Mining Bureau of Taiyuan all coal seams belong to more than 2.5% sulfur content of high-sulfur coal seam. Sulfur content, iron sulfide accounted for 60%, 40% of organic sulfur. Of the five high-sulfur coal seams currently being mined, the fourteenth layer of coal gangue is dominated by iron sulfide and has a non-continuous distribution of nodules. The minimum size of iron sulfide is 50 mm and the maximum is 300 mm, generally about 100 mm. Iron sulfide to a small amount of star-like, flaky existence; 17 and 18 layers to star-shaped existence. The high-sulfur coal seams are all thin coal seams with a thickness of less than 1.3 meters, and are governed by the longwall method. Although the past used roller drum unit, plow and coal and other equipment,
