由我院科研所和煤炭科学研究院北京开采所、沈阳矿务局共同承担的“本溪沈丹铁路干线下采煤的研究”课题,于1985年12月通过了由煤炭科学研究院组织的专家技术鉴定.沈丹铁路是我国东北重要的国际干线之一,是国家Ⅰ级干线.铁路煤柱自1978年11月开始试采到1985年10月止共采出煤炭67.7万吨.获得直接经济效益314万元.采后路基最大下沉、最大横向水平移动以及最大下沉速度均能保证铁路运输的安全畅通.试采取得了
The project “Research on Coal Mining Under the Benxi Shen-Dan Railway Trunk” jointly undertaken by the Institute of Coal Mine Sciences and the Beijing Mining Institute of Coal Science Research Institute and Shenyang Mining Bureau passed the experts organized by the Coal Research Institute in December 1985 Technical appraisal.Shendan Railway is one of the important international trunk lines in northeast China and is a national Class I. The coal pillar of the railway has been tested and started production in November 1978 to a total of 677,000 tons of coal since October 1985. Access to direct economy Benefit 3.14 million yuan.After the mining subsidence maximum sinking, the maximum lateral horizontal movement and maximum sinking speed can ensure the safety and smoothness of railway transport.
