在露天矿大倾角区域进行排土，当排弃参数不变条件下采用麻面爆破方法处理基

Dumping in the large dip area of ​​the open-pit mine. When the basement is treated by the pockmarked blasting method under the condition of constant disposal parameters, the blasting depth affects the stability of the dumping step. If the depth is large, the mechanical properties of the basement rock formation are greatly weakened , Forming a weak layer, reducing the anti-sliding force of the dumping steps, increasing the anti-sliding force of the dump, which is not conducive to the stability of the dump.

In the open-pit mine large inclination area for soil draining, when the disposal parameters do not change the conditions of the use of hemp blasting method to deal with the substrate, blasting depth affects the stability of the draining steps, if the depth is large, so that the base rock layer of the regenerological properties greatly weakened, forming a weak layer, reduce the anti-slip force of the draining steps, increase the anti-slip force of the drain site, is not conducive to the stability of the drain.

When dumping is carried out in the large inclined area of open-pit mine, when pit blasting method is adopted to treat the base under the condition of constant dumping parameters, the blasting depth will affect the stability of the dumping step. If the depth is large, the mechanical properties of the base rock will be greatly weakened, and the weak layer will be formed, which will reduce the anti sliding force of the dumping bench and increase the anti sliding force of the dump, which is not conducive to the stability of the dump.<br>
