露天矿生产能力分析

 文中给出了单斗—卡车工艺推进度的数学模型和制约露天矿推进度的因素，并对这些影响因素进行了分析，得出了相互作用曲线；同时根据模型和图像分析，提出了优化单斗—卡车工艺工作线长度和增大电铲工作时间来提高露天矿推进度的措施，从而达到提高矿山产量的目的。最后以别斯库都克露天煤矿为例，对其在采区变化后工作线变短条件下的最大推进度及最大产量进行了设计计算。

Analysis of stabability of jointed Rock Slopes Unloading

According the analysis foundation of the jointing tension or presses the different condition, uses the stress adjustment jiont to open, the strain control jiont closed criterion separately, has established the double jointing rock slope model which using the abaqus software, the rock mass contains two sets of planes of weakness: one vertical set of joints and one set of inclined joints. and has carried on the simulation analysis to this jointing rock s slope's stability. Through this method to the jointing rock slope slide process's simulation, obtained the slope body's slipping failure plane intuitively, had proven the jointing controls the primary factor which the rock slope destroys. Forms the mechanism regarding the understanding slope's destruction to have the important meaning. Which explained that this criterion can forecast accurately the jointing rock slope latent failure plane’s shape and position, may provide the corresponding theory regarding the complex rock slope stability analyses.
