在同一水平层3条电耙道同时扒矿的分风问题,已经有较成熟的经验。但在同一水平层5条电耙道以上扒矿的合理分风,仍然不够成熟。为了寻找多电耙层的合理通风系统及分风措施,我们从采用中深孔阶段强制崩落采矿法以来,进行了一些摸索对比。一、几种方案比较 (一)垂直矿体走向布置电耙道层,上向风流进风,水平风流回风。进风井位于底板,回风井位于顶板。这种电耙道布置方案如图1所示。其主要缺点是:
In the same level of three electric rake Road at the same time the grill mine air, there have been more mature experience. However, in the same level of 5 electric rake more than the reasonable grill wind, is still not mature enough. In order to find a reasonable ventilation system for multi-rake layer and the wind separation measures, we have made some groping contrastive studies since adopting the forced caving mining method in the middle-deep hole stage. A comparison of several programs (A) Vertical ore body to the layout of electric rake layer, the wind into the wind, the level of wind back to the wind. Intake air shaft is located in the floor, return air shaft is located in the roof. This electric rake layout shown in Figure 1. Its main drawback is:
