摘  要
本设计包括三部分：一般部分，专题部分和翻译部分。
一般部分为平煤集团十矿0.45Mt/a新井设计，共分十章：矿井概述及井田地质特征，井田境界和储量，矿井工作制度、设计生产能力及服务年限，井田开拓，准备方式—采区巷道布置，采煤方法，井下运输，矿井提升，矿井通风及矿井基本技术经济指标。
平煤集团九矿井田位于平顶山煤田西部，平顶山市西北部，距市区中心约15 km，行政区划平顶山市新华区。区内地势较为平坦，井田东西走向长度2.06千米，南北倾斜方向长1.88千米。面积为3.63平方千米。井田可采煤层主要为己15煤层。厚度分别为6.5米。煤层倾角平均为20度。井田可采储量为5116万t，新井设计生产能力为0.45Mt/a，服务年限为56年。
平煤集团九矿矿井工作制度为“三八”制，一个工作面保产。开拓方式为双斜井三水平开拓，水平标高分别为-300、-500、－650。矿井主斜井采用皮带输送机运煤，副斜井采用双钩提升作辅助提升。工作面采用走向长壁采煤法，工作面长约150米，采煤工艺为综采开采。矿井运煤在大巷中采用皮带输送机运输，辅助运输采用1吨固定式矿车运输。矿井采用中央并列式通风，主扇工作方式为抽出式。
专题部分为AutoLISP在采矿柱状图绘制中的应用。
翻译部分介绍了采用三维物理建模方法研究软岩巷道的支护强度。实验性研究得到了一系列的支护强度，并说明存在一个合理的支护强度。其作用取决于井巷围岩的地质受力情况，取决于对井巷的合理利用，取决于井巷服务年限。研究还表明，对于中等尺寸、压力在20Mpa，埋深在500m的井巷，0.3至0.5MPa的支护强度可获得变形速率0.1~0.4mm/d。

ABSTRACT

This design includes of three parts: the general part, special subject part and translation part.
The tenerally part of for Pingdingshan group JiuKuang 450,000 ton the new well design, total is divided into ten:The mineral well says all and the well farm land quality characteristic, the well farmland state with keep quantity, the mineral well work system,design produces the ability and the service time limit, the well farmland expand, prepare a way-adopt the area tunnel decoration, adopt the coal method, the well descends a conveyance, the mineral well promote, the mineral well airiness and the mineral well basic technique economic index sign.
Pingdingshan group ninth mineral well farmlands locate an even crest the mountain coal field western region, even crest northwest in mountain City, be apart from the downtown center about the 15 km, the administrative area rows an Pingdingshan City XinHua District.The area hinterland is certainly more plant, the well farmland thing alignment the length is 2.02 kilo-meters, the south north tilt to one side the direction grow 1800 meters.Area is 3.63 the squares is personal 15 coal seamses mutually.The coal seam  Cape equally is 20 degrees.The well farmland can adopt to keep the quantity as 51,160,000 tons, the new well design produces an ability for 450,000 tons/years, the service time limit is 56 years.
Pingdingshan group ninth mineral well work systems for"38" make, one work noodles protect to produce.Expand a way for  the double inclined shaft Erh-shui even expand, the level elevation respectively is-300,-450,-710.The mineral shaft adoptes belt conveyor that lifts coal, the vice- shaft adoptes bottle the car Be an assistance to promote.The work noodles adoption alignment long the wall adopt the coal method, work the noodles grow 150 meters, adopting the coal craft to adopt to mine for the.The mineral well luck coal adopts the 3 T mineral car conveyance in the big lane, the assistance conveyance adopts 1.0 tons fixed the type mineral car conveyance.The mineral well adoption sperate angles type is well ventilated, main work method for draw out type.
The special subject part of topics is The optimal support intensity for coal mine roadway tunnels in soft rocks
Translate part introduces that The three-dimensional physical modelling method provides a `conceptual approach to quantitative design' of roadway support associated with soft rocks. With lack of knowledge of the constitutive relations, especially for the rheological mechanisms, in rock engineering practice, the modelling results could serve as a foundation on which a scientic design of underground roadway/tunnel support is developed, particularly when a large amount of rock mass deformation is concerned. The experimental study conducted with a series of support intensities revealed that a reasonable support intensity exists.
