摘　　要：针对卡房西凹矿段矿体围岩结构复杂、稳固性较差的特点,通过工程地质调查,对矿体的产状、赋存条件、品位等进行分类统计,并结合矿山实际情况对矿体分区。在建立采矿方案综合评价指标体系的条件下,将关联矩阵法和采矿理论相结合,确定富矿体及较富矿体的最优采矿方案为上向分层充填法,贫矿体的最优采矿方案为分段空场法。实际工程运用后,西凹矿采场综合损失贫化率降低至15%以下,采场生产成本较之前约降低了10%,矿段内综合生产能力达到了350t/d。In view of the complex structure and poor stability of the surrounding rock of the ore body in Kafang Xiwa ore section,the occurrence,occurrence conditions and grade of the ore body were classified and counted through engineering geological investigation,and the ore body is divided according to the actual situation of the mine.Under the condition of establishing a comprehensive evaluation index system for mining schemes,the correlation matrix method and mining theory were combined to determine that the optimal mining scheme for rich ore bodies and relatively rich ore bodies was the upward layered filling method,and the optimal mining scheme for poor ore bodies was the sublevel open stoping method.After the actual engineering application,the comprehensive loss and dilution rate of the stope in Xiwa Mine was reduced to less than 15%,the production cost of the stope was reduced by about 10%compared with the previous,and the comprehensive production capacity in the ore section reached 350t/d.
