Checking and Accepting the Peel off of Strip Mine By Section Stadia and Analyzing the Precision

年剥离量为2823万吨，采矿石797.8万吨，是目前我国单体矿山年产量最高的矿山。

The mine is the highest monomer mine in our country with Stripped volume amount as 2.823 million tonnes and exploitation amount as 7978 thousand tonnes annual .

不仅减少了矿山剥离量，确保了矿山生产的安全，同时也保护了边坡外大片良田免受边坡坍塌破坏。

It can not only reduce the stripping amount and guarantee the safety of production , but also prevent the fertileland neighboring the side slope from collapsing and damaging .

该边坡形状与传统的稳定性理论确定的边坡形状相比较，可在保证边坡稳定的前提下减少巨大的废石剥离量。

A great quantity of stripped waste rock can be reduced by the slope configuration determined by the proposed model , as compared with that determined with the traditional theory of slope stability .

新模型有效支持了陡帮开采，增大了边坡最终边坡角，减少无效剥离土石量3%～5%；

With safety and reliability , the new mode sustains steep slope mining , increases the angle of ultimate slope , and reduces 3 % ~ 5 % of noneffective overburden amount .

露天矿采用抛掷爆破技术，可将大量剥离物抛入采空区，使拉斗铲剥离量大为减少，剥离成本大幅度降低。

By using the casting blast technique in surface mines , a large volume of overburden will be thrown into the mined-out area , making the stripping volume of dragline operation be decreased and the stripping cost lowered .
