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3.83m，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 2，400,000 tons of coal annually to be designed, whose coal bed gives deeper layer and inclination is not lager, the average thick is about 3.83m, 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 mechanization，adopt advanced techniques and use for reference afterwards realize high yield highly active modernization shaft 'experience，realize one mine not both high yield highly active shaft thereby run up to favorable economic benefit and social benefit.

Keywords: explore ways preparation ways coal mining methods

mechanization comprehensive high yield highly active
