由煤炭科学院唐山分院、鹤壁矿务局承担的“六、五”科技攻关延续项目——“特厚煤层综采水落顶煤工艺及设备”的课题,经九个月的工业性试验,已获重要的技术突破。 在特厚煤层进行机械化开采的工艺,世界上许多国家都在探讨,现在尚未见到适合我国需要的成功报道。我国的煤炭科研人员于1982年提出了分两层自上而下开采的工艺方案,经严密的科学论证后,于1986年4月开始在鹤壁矿务局六矿进行工业性试验。试验在8～12米煤层中进行,第一阶段是顶分层开采,全部采
The “Sixth Five-Year” scientific and technological extension project undertaken by Tangshan Branch and Hebi Mining Bureau of the Academy of Coal Science - the project of “Technology and Equipment of Fully Mechanized Coal Mining with Top-Coal at Fully Mechanized Coal Mining” has been approved by the industrial test for nine months Important technological breakthrough. Many countries in the world are exploring the mechanized mining technology in the thick coal seams and have not yet seen successful reports suitable to our country’s needs. In 1982, China’s coal researchers put forward a two-layer top-down mining process plan. After rigorous scientific verification, the industrial experiment began at the No.6 Mine of Hebi Mining Bureau in April 1986. The experiment was carried out in 8 to 12 meters of coal seam. The first stage was the top stratified mining, all mining
