露天矿开采技术课程诊断与改进实践

以全国高职院校推广教学质量诊断与改进工作为背景,对露天矿开采技术课程进行了诊断与改进,通过诊断发现了课程建设及教学过程中存在的不足,对课程进行了项目化开发,对课程教学方案进行了优化设计并对课程教学资源进行补充完善,制订了课程评价及持续改进保障体系。该课程的成功诊改,为学校其它课程的诊改提供了成功的借鉴和宝贵的经验,可推进整体教学质量诊改进程。

深凹金属露天矿开采技术优化与危险源辨识风险评价研究

目前,为了提高我国露天矿山开采效率,减少安全事故的发生,已经转化为了深凹型露天矿。但是,开采环境和方式的改变,对矿山开采技术也提出了更高的要求,为了减少安全事故的发生,保证矿山开采的安全性。基于此,对超-深凹金属露天矿开采的相关环境进行了,保证此工程进行的顺利性和安全性,加强了对危险源的识别以及风险评价,希望能够为相关学者提供借鉴价值。

STUDY ON THE RECLAMATION TECHNIQUE IN A SURFACE MINE WITH CROSS-PIT SYSTEM

A cross-pit system (CPS) could combine the excavation of coal and the reclamation of land together, thus it has been widely used in many countries. Based on a field experiment at Horse Creek mine in Illinois State of the United States, this paper deeply studies the reclamation technique of surface mining by a CPS and comprehensively evaluates its reclamation effect. Problerns and improvements of the reclamation technique are also discussed in this paper.
