【摘要】 大厂铜坑锡矿在国内率先使用块石砂浆胶结充填法。为了探明块石砂浆胶结充填的可行性，为工业性试验提供依据，进行了地表模拟试验，并在此基础上进行了工业试验。本文介绍了这一技术的试验研究情况。结果表明块石充填体力学性能好，强度高，可保证回采安全；充填能力大，成本低，可推广使用。更多还原

【Abstract】 The first use of cemented fragmental rock filling in China was conducted atTongkeng tin mine operated by Dachang Mine Bureau. In order to prove the feasibility ofcemented fragmental rock fiIIing and provide the basis for the industrial test,a simulationtest carried out on the ground and a industrial test based on the fOrmer were made. The ex-perimental study on this technology is presented in this paper. The test results have shownthat the cementd fragmental rock filling body is good in mechanical characteristics andhigh in strength as well as can ensure safe stoping. This method can be deployed, due toits high capacity of filling and low cost更多还原
