摘　　要：在开发地质勘测中发现冬瓜山矿床42线以南矿体变薄,矿体特征与初步设计阶段有较大差异,原来设计的采矿方法需要改变。在前期采矿方法研究成果基础上,通过综合研究,筛选并推荐"无底柱阶段空场嗣后充填法铲运机出矿方案"进行工业试验,后续应在上述建议方案的基础上,结合开拓、采准信息,进一步修改制定实施方案,应用成熟后再推广。In the exploitative geological exploration it is found that the orebody in the south of 42 line of Dongguashan deposit gets thinner and the actual orebody characteristics are quite different from the previously predicted in the primary design stage. So the mining method designed previously needs to be updated. Based on the previous research achievement of mining method, stage open stoping followed by back filling without pillar was selected out and proposed for field test. In the basis of test results, it was also proposed that an implementing scheme should be made by combing the development and mining preparation information. The popularization of this scheme should follow the successful application.
