文档介绍：采矿专业毕业论文--吕家坨煤矿初步设计
摘要
本设计是根据河北省开滦集团吕家坨矿的实际情况进行的初步设计设计的井田面积为41平方公里矿井年产240万吨井田内煤层赋层较深倾角不大平均厚383m瓦斯涌出量相对较小煤层有自然发火倾向矿井涌水量一般
设计采用立井两水平暗斜井延深开采的开拓方式采用条带式准备方式采用倾斜长壁采煤方法综合机械化一次采全高的回采工艺用全部跨落法处理采空区主要对矿井开拓方式准备方式采煤方法进行了初步设计对矿井运输通风排水等生产系统进行了设备选型计算对矿井各个生产系统的生产过程进行了描述并对矿井各个生产系统和各生产环节之间的相互联系和制约关系进行了有关说明在设计过程中尽量采用先进的技术和设备矿井全部实现机械化采用先进技术和借鉴已实现高产高效现代化矿井的经验实现一矿一面高产高效矿井从而达到良好的经济效益和社会效益
关键词开拓方式准备方式采煤方法综合机械化高产高效
ABSTRACT
The designation is based on actual situation of Lu Jiatou pit of the Kailuan Mining Group in Hu beifor the the preliminary design There are 41 square kilometres of well field area and tons of coal annually to be designed whose coal bed gives deeper layer and inclination is not lager the average thick is about 383m geological structure is simple the volume of gas poures out relatively larger coal bed has natural fireing tendency and the colliery water is middle in cacity
This design adopts the erected sheft mining method and belt-ready way In addition to using skewed towards long walland methods integrating mechanized stoping techniques That is the main way to open up the pit preparing forms coal mining methods for preliminary design As well as transport ventilation drainage systems and other production equipment models calculated to pit various production systems described in the production process Besides I want to describe various production systems of the pit and the interlinkages between the production relations and the constraints on the statement In the design process both shaft whole realize mechanizationadopt advanced techniques and use for reference afterwards realize high yield highly active modernization shaft experiencerealize one mine not both high yield highly active shaft thereby run up to favorable economic benefit and social benefit
