矿井建设和生产过程中经常遇到这样的问题:在人力物力一定的条件下,如何安排计划才能完成最大可能完成的任务?在完成给定任务的前提下,如何筹划才能消耗最少的人力物力等资源?借助于系统工程中的一个重要组成部分——线性规划,我们可以在诸约束条件中求得所追求目标的最优解。现以安阳矿务局红岭井为例简要说明规划论的数学模型建立和解算方法。 红岭井为一技术改造矿井。新水平-140米水平工程由三个园班组在施工。月进度要求:-140米运输巷不低于70米;该运输巷的配风巷不低于120米;主下山下车场不低于50米。另于井田南部边界处新开一风井,作为新水平的出风井和安全出口,月进度要求不低于30米。各井巷的劳动力、材料消耗定额,提升运输限额以及单位造价如表一所示。某月施工计划拟安排300米成巷任务,准备了炸药7吨、雷管11200个、金属锚杆6100根、水泥400吨、坑木80米~3、计划投入劳力8300工日,同时提升设备为上述井巷誊出了
Mine construction and production process often encounter such a problem: In the human and material resources under certain conditions, how to arrange the plan to complete the task to be completed? In the premise of the completion of a given mission, how to plan to consume the least manpower and resources Resources? With the help of linear programming, an important part of systems engineering, we can find the optimal solution of the goal to be pursued in all the constraints. Now Anyang Mining Bureau Hongling well as an example to briefly explain the mathematical model of planning theory and solution method. Hongling well as a technological transformation of the mine. The new level of -140 m horizontal project by the three park team in the construction. The monthly progress requirements: -140 m transport lane not less than 70 meters; the lane of the air Lane not less than 120 meters; the main downhill yard of not less than 50 meters. In addition, a new wind shaft was opened at the southern border of Ida. As a new level of air outlet and safety exit, the monthly progress requirement is not less than 30 meters. The labor force and material consumption quotas of various shaft and laneways, as well as the increase of transport quotas and the unit cost, are shown in Table 1. A month’s construction plan to arrange 300 meters into the alley task, prepared 7 tons of explosives, detonators 11200, 6100 metal anchor, 400 tons of cement, pit 80 meters to 3, plans to put labor 8300 days, while upgrading equipment The above roadway dug out
