摘要： 矿山采掘计划编制对企业总体经济效益具有深远的影响，手动编制技术已难以满足矿山的需求.为有效提高计划编制的高效性和合理性，通过对无底柱分段崩落法的研究分析，建立了以出矿品位波动最小为目标函数的混合整数规划(MIP)模型.模型包含了生产开采的全过程，以保证井下各工序的合理衔接.对北洺河铁矿采掘计划编制的试验结果表明，该方法具有编制时间短、工序衔接更合理、计划结果较手动方法更优越的特点.研究表明采用该方法能有效提高计划的合理性，使企业获得更大经济效益.

Abstract: Production scheduling has a profound influence on the overall economic benefits of the mining enterprise， and the manual technology has difficulty to meet the needs of mine. To improve the efficiency and rationality of scheduling， we studied the non-pillar sublevel caving method， and presented a mixed integer programming (MIP) model. This model makes minimum fluctuations of ore grade as the objective function， and it contains the whole process of mining to ensure all procedure could be more reasonable connected. In the test of the production scheduling of the Beiminghe iron mine， the results show that it spent shorter time and the procedure was more reasonable， what′s more， the results are better than the manual method. The study shows that this method can effectively improve the rationality of schedule and make the enterprise get more economic benefits.

Key words: underground mine, non-pillar sublevel caving method, production scheduling, mixed integer programming, minimum fluctuations of ore grade
