 This paper deals with the optimization of mining scheme planned for longwall mining advancing along an inclination. In this case, the authors propose that the criterion for optimization should be characterized as the cost per ton of coal,i.e. the less the cost, the best the scheme. A mathematical model including six variables is presented. And 1080 schemes were put into the computer and solved. The results arc shown in two nomograms. These nomograms provide a versatile and powerful means for finding out... This paper deals with the optimization of mining scheme planned for longwall mining advancing along an inclination. In this case, the authors propose that the criterion for optimization should be characterized as the cost per ton of coal,i.e. the less the cost, the best the scheme. A mathematical model including six variables is presented. And 1080 schemes were put into the computer and solved. The results arc shown in two nomograms. These nomograms provide a versatile and powerful means for finding out the optimum layout of roadwaysystem for inclined longwall mining, if the following parameters are known: numbcr of coal scams, vertical distances between coal scams, size of working area and maintenance cost of coal roadways.  本文阐述的评价倾斜长壁开采方案的准则为吨煤费用最小。提出的数学模型中,设有6个变量。借助于电子计算机,对1080个方案进行了计算。计算结果表示在两个诺谟图中。根据煤层数目、层间距、采区尺寸及煤层巷道维护费,可以从图中很快找出一个倾斜长壁开采的最优布置方案来。  This paper deals with the problem of how the optimal procedure for locating tha extreme point of a unimodal objective function by sequential tests is determined when some probability information of the random objective function is known.
