禹州市吕沟煤矿在薄煤层采用高档普采获得成功,并于1993年9月10日通过省煤炭厅验收,从而开创了我省薄煤层推广高档普采的先例。 1992年9月,吕沟煤矿使用国产高档普采设备,在五_2煤层601采面一次试采成功。经过近一年的试采,各项指标均达到了设计要求。特别是单产、工效达到了全国同类煤层较好水平,河南省地方国有煤矿最高水平。 与炮采相比,高档普采月产量提高65％,工效提高85％,吨煤成本下降54％、减员26％、平均创经济
The Lugou Coal Mine in Yuzhou succeeded in adopting high-grade general mining in the thin coal seam and passed the inspection of the provincial coal hall on September 10, 1993, thus setting a precedent for the promotion of high-grade general mining in the thin coal seam of our province. September 1992, Lvgou coal mine using domestic high-grade universal mining equipment, coal mining in the 601 coal seam a successful trial. After nearly a year of trial mining, the indicators have reached the design requirements. In particular, yield, industrial efficiency has reached a better level of similar coal seams, Henan Province, the highest level of state-owned coal mines. Compared with artillery mining, high-end general-purpose mining increased by 65% per month, work efficiency increased by 85%, 54% reduction in tonne coal costs, 26% downsizing, the average economy
