北宿煤矿1976年投产,属三类型极薄煤层矿井。当时生产工艺甚为落后,靠放炮落煤,人工攉煤。建矿10多年来,一直十分注重科技进步成果的应用,曾进行过采煤机械化的探索。由于矿井平均采高只有0.9m,煤层中含有硫化铁及不规则的硬质夹矸,多次进行采煤机械化试验,都未能成功。 1986年积极响应煤炭部大搞现代化矿井的号召,先后组织人员到鸡西、七台河、峰峰、肥城、徐州等局、矿和石家庄、淮南、兖州煤机厂进行机采调研,制定了采煤机械化 Beisun coal mine put into operation in 1976, is a three types of very thin coal seam mine. Production technology was very backward at that time, by firing coal, artificial coal. For more than 10 years since the founding of the mine, the application of achievements in scientific and technological progress has been paid great attention. Coal mining mechanization has been explored. As the mine average mining height is only 0.9m, the seam contains iron sulfide and irregular hard gangue, coal mechanization test several times, have failed. Actively responding to the call of the coal ministry in 1986 to mobilize the modernized mines, it successively organized personnel to carry out mechanical mining research on Jixi, Qitaihe, Fengfeng, Feicheng and Xuzhou coal mines and coal mines in Shijiazhuang, Huainan and Yanzhou, Coal mechanization
