河南省煤研所在科技体制改革的进程中,调动了科技人员的积极性,86年有六项成果通过鉴定或评议。 受省科委委托,由省厅组织,邀请煤炭部有关主管领导部门、省内外生产基建单位、高等院校和科研、设计单位的学者、专家进行鉴定的项目有:1.黄门煤矿厚煤层前进式开采及沿空留巷巷道支护改革试验研究,通过该项试验研究,取得了缩短采准时间、缓和采掘失调、生产系统畅通稳定、提高煤炭资源回收率以及显著节约坑木等经济效益,并可在低沼、不易自燃发火、顶板破碎但地质条件较稳定的类似矿井推广使用;2.高效球齿钎头研制。由于采用了新型硬质合金材料、钎头几何结构及加工、热处理工艺均较合理,因此与其他钎头试验对比表明,此种钎头具有穿孔效率高、耐磨等显著特点,预计不仅能在国内市场具有竞争力,还可望在进一步研制后打入国际市场;3.钢丝绳牵引单轨吊车该G DD-140型单轨吊,结构与国际上单轨吊研制水平较领先和使用也最广泛的西德的同类型单轨吊大体相似,但有所简化,且在某些关键部件上又有所改进提高,其信号电控部分也简化并选用造价低廉、工作可
Coal Research Institute of Henan Province in the process of reform of science and technology system, to mobilize the enthusiasm of scientists and technicians, 86 six have passed the appraisal or appraisal. Commissioned by the provincial Science and Technology Commission, organized by the ministries and agencies, invited the competent leadership departments of the Ministry of Coal Industry, provinces and regions outside the province to produce infrastructure units, institutions of higher learning and scholars, experts in scientific research and design units to carry out the identification of the project are: 1. Huangmeng thick coal seams Through the pilot study, we have achieved the economic benefits of shortening the quasi-mining time, alleviating the mining disturbance, smooth and steady production system, improving the recovery rate of coal resources, and saving pit trees significantly , And in low marsh, not easy to spontaneous combustion, roof crushing but similar geological conditions more stable promotion of the use of coal; As a result of adopting the new cemented carbide material, the geometric structure of the drill head, the processing and the heat treatment process are all reasonable, the comparison with other drill bits shows that the drill head has notable features such as high perforation efficiency and wear resistance, The domestic market is competitive, is expected to enter the international market after further development; 3. Rope towed monorail crane The G DD-140 type monorail crane, structure and international monorail research and development level than the leading and most widely used in the West The same type of monorail in Germany is generally similar, but has been simplified, and some of the key components have improved and improved, the signal control part is also simplified and selected low cost, work can be
