为了解决倾斜、缓倾斜中厚矿体采矿方法的难题,提高采场生产能力,降低生产成本,锡矿山粗颗粒水砂充填采矿方法的试验研究被列为国家“七五”重点科技攻关项目,由北京矿冶研究总院和锡矿山矿务局协作共同进行攻关。通过四年多的试验研究,圆满地完成了国家“七五”重点科技攻关任务的要求。1991年1月18～21日,中国有色金属工业总公司在锡矿山矿务局主持召开了鉴定和验收会,组成了21人的专家评审组,对该项科研成果进行了鉴定和验收。专家们经过了认真地评审一致认为,该课题研究是成功的,取得了多项科研成果,整体上达
In order to solve the problems of inclined and moderate inclined ore body mining methods, improve the production capacity of stope and reduce the production cost, the experimental research on the method of coarse grain water sand filling and mining in tin mines is listed as the key scientific and technological project of the “Seventh Five-Year Plan” By the Beijing Mining and Metallurgical Research Institute and Colliery Mining Collaboration to tackle key problems. After more than four years of experimental research, the requirements of the key scientific and technological tasks of the state for the Seventh Five-Year Plan have been satisfactorily completed. From January 18 to January 21, 1991, China Nonferrous Metals Industry Corporation presided over the appraisal and acceptance meeting hosted by the Xikuang Mining Bureau and formed a 21-person expert review team to appraise and check the scientific research achievements. After careful assessment of the experts agreed that the research is successful, has made a number of scientific research, as a whole
