1、 本科本科课程课程设计设计说明书说明书 学生姓名： 指导教师： 专业班级： 学 号： 时 间：2014.12 综合成绩： I 摘要 本文为露天课程设计说明书，某煤田矿位于内蒙西部地区，煤层呈单斜赋存，煤层倾 角 40，平均水平厚度为 47m。剥离物上部为沙土层平均厚度 7m，顶板岩层由两层构成， 上部为砂页岩，下部为砂岩，底板岩层自上而下由泥页岩和砂页岩构成。 介绍了从煤田地质概况，露天矿合理帮坡角确定，在认识地形图的基础上试算并确定 最终帮坡角，露天开采境界，开采工艺选择及设备选型，确定开采参数和开采程序，用煤 岩累计值画出 v=f（p）曲线；依据所绘曲线确定投、达产点并进行剥采比均衡，算出

2、均衡 后的剥采比以及均衡年限，开拓运输系统，确定主要设备数量，最后，绘制出达产后某一 时期的工程位置平面图。 目的是让我们学习露天设计的过程。 设计成果：课程设计计算说明书一份，露天矿开采最终平面图（A0 图纸一张） ，露天 矿开采境界横断面图（A0 图纸一张） 。 关键词：露天开采；开采工艺；设备选型；开采参数；开采程序； v-p 曲线绘制及生产剥 采比均衡 II Abstract This paper is designed to open course manual, a coal mine is located in the western In ner Mongolia area,

3、coal seams are monoclinic occurrence, coal seam dip angle is 30 , the a verage thickness of 47m. The overburden abovethe average thickness of sand layer 7m, roof i s composed of two layers, the upper sand shale, sandstone rock bottom lower part, from top to bottom byshale and sand shale. Introduced

4、from the coalfield geology, slope angle to determine reasonablehelp open pi t mine, based on knowledge of topographic map on trial anddetermine the final slope angl e, pit, selection of mining technology andequipment selection, the determination of mining p arameters and miningprocess, coal rock acc

5、umulated value draw v=f (P) curve; on the basis of thepainting curve to determine the investment, production and stripping balance,calculate t he balance after the stripping ratio and balanced life, development and transportation syste m, determine the main equipment quantity, finally,draw the engin

6、eering location plan after a certain period of time. The purpose is to let us learn the open design. Results: the curriculum design of a manual design calculations, open-pit mining final pl an (A0 drawings a), open-pit mining realm cross-sectional diagram (A0 drawings a).
