答案：【计分规则】: When part of a hillside is deep, the direction of extension is usually the same as the inclined direction of the hillside, which can reduce the amount of preparation work for new level development. In order to reduce the amount of capital construction and speed up the construction of open pit, the depth along the roof or floor of the ore body can be extended, and the angle of extension is consistent with the dip of the ore deposit. The depth can also be extended along the boundary direction, at which time the depth angle is consistent with the final slope angle.
