露天采矿场采掘推进方向,主要取决于矿区的地形、矿床赋存特点及开采运输条件。采用汽车运输的露天矿,汽车运输距离是影响汽车生产能力和矿石开采成本的重要因素。而汽车运输有灵活机动的特点,在条件允许时,可以改变掌子面形状、改变采掘推进方向,来缩短汽车运距,尽可能实现矿岩的水平运输,避免或减少重车上下坡行驶,达到多快好省地开采矿石的目的。这在技术上是可行的,在生产上是可
The direction of mining excavation in open pit mining depends mainly on the topography of the mining area, the characteristics of ore deposits and the mining and transportation conditions. The use of motor transport of open-pit mines, car transport distance is an important factor affecting the car production capacity and ore mining costs. The motor transport has a flexible and mobile features, when conditions allow, you can change the face shape, change the direction of mining and advancing, to shorten the car away from the mine, as far as possible to achieve the level of transport, to avoid or reduce heavy truck driving downhill, To achieve more rapid and economical ore mining purposes. This is technically feasible and production-wise
