摘要
本设计包括三个部分:一般部分、专题部分和翻译部分。
一般部分为涡北煤矿1.20 Mt/a新井设计。涡北煤矿位于安徽省亳州市境内,东有京九铁路,西有濉阜铁路,交通便利。井田走向长度约6.3 km,倾向长度约3.1 km,面积约14.5km2。主采煤层为8号煤层,平均倾角为17°,平均厚度为7.5 m。井田工业储量为146.73Mt,可采储量为80.95 Mt,矿井服务年限为51.9 a。矿井正常涌水量为320 m3/h,最大涌水量为360 m3/h。矿井绝对瓦斯涌出量为21.33 m3/min,属于低瓦斯矿井。
根据井田地质条件,提出四个技术上可行的开拓方案。方案一:立井两水平开拓上下山开采,暗斜井延深;方案二:立井两水平开拓上下山开采,立井直接延深;方案三:立井两水平开拓上山开采,暗斜井延深;方案四:立井两水平开拓上山开采,立井直接延深。通过技术经济比较,最终确定方案三为最优方案。一水平标高-700 m,二水平标高-1000 m。
设计首采区采用采区准备方式,工作面长度150 m,采用综采放顶煤采煤法,矿井年工作日为330 d,工作制度为“四六制”。
大巷采用胶带输送机运煤,辅助运输采用矿车运输。矿井通风方式为中央并列式。
专题部分题目:松软破碎巷道注浆加固加护:煤矿软岩巷道工程是软岩工程的一个重要组成部分。软岩工程是指与塑性大变形岩体有关的岩体工程,如软岩边坡,软岩隧道及软岩巷道工程等。由于软岩巷道工程所处的复杂工程地质条件,其支护问题一直是困扰我国煤炭生产的一个主要问题。本文系统论述了软岩的定义、工程地质特征和力学属性,分析了软岩巷道围岩的变形破坏特征及影响因素;就注浆加固技术国内外研究现状及目前存在的问题进行分析探讨;深入分析了围岩锚注加固机理;最后对松软破碎巷道注浆加固技术工程应用进行了设计。
翻译部分题目:The application of modern surveying technology in mining.
现代测量技术在采矿中的应用。

ABSTRACT
This design can be divided into three sections: general design, monographic study and translation of an academic paper.
The general design is about a 1.20 Mt/a new underground mine design of Wobei coal mine.Wobei coal mine lies in Hozhou City, Anhui province.As Jingjiu railway runs in the west of the mine field and Suifu railway runs in the east of the mine field, the traffic is convenient.It’s about 6.3 km on the strike and 3.1 km on the dip, with the 14.5 km2 total horizontal area.The minable coal seam is 8 with an average thickness of 7.5 m and an average dip of 18°.The proved reserves of this coal mine are 146.73 Mt and the minable reserves are 80.95 Mt, with a mine life of 51.9 a. The normal mine inflow is 320 m3/h and the maximum mine inflow is 360 m3/h. The mine gas emission rate is 21.33 m3/min, the mine belongs to low gas mine.
Based on the geological conditions of the mine, I bring forward four available projects in technology.The first is vertical shaft development with two mining levels and the first level at -700m and the second level at -850m and extension of blind inclined shaft; the second is vertical shaft development with two mining levels and the first level at -700m and the second level at -850m and extension of vertical shaft; the third is vertical shaft development with two mining levels and the first level at -700m and the second level at -1000m and extension of blind inclined shaft; the last is vertical shaft development with two mining levels and the first level at -700m and the second level at -1000m and extension of new vertical shaft. The third project is the best comparing with other three projects in technology and economy.The first level is at -700 m.The second level is at -1000 m.
Designed first mining district makes use of the method of the mining district preparation.The length of working face is 150 m, which uses fully-mechanized coal caving mining method. The working system is “four-six” which produces 330 d/a.
Main roadway makes use of belt conveyor to transport coal resource, and mine car to be assistant transport. The type of mine ventilation system is center ventilation.
The translated academic paper is The application of modern surveying technology in mining Keywords: Vertical shaft; Blind inclined shaft; Mining district preparation; Coal caving mining ; Center ventilation; Gob-side entry rataining
