千秋煤矿200万吨新井通风安全设计 - 毕业设计 - 图文(2)

摘 要

本设计包括三个部分：一般部分、专题部分和翻译部分。

一般部分为芦岭矿120万吨/年新井设计。芦岭矿位于安徽省淮北市，交通便利。井田走向（南北）长约7.67km，倾向（东西）长约4.52km，井田总面积为46.39km2。主采煤层为8号煤，平均倾角为18，煤层平均总厚为9.25m。井田地质条件较为简单。

井田工业储量为14692.7万吨，矿井可采储量10578.3万吨。矿井服务年限为63年，涌水量不大，矿井正常涌水量为75m3/h，最大涌水量为120m3/h。矿井瓦斯涌出量较高，为高瓦斯矿井。

井田为立井单水平开拓。大巷采用胶带运输机运煤，辅助运输采用无轨胶轮车设备。矿井通风方式为中央分列式通风。

矿井年工作日为300d，工作制度为“四六”制。

一般部分共包括五章：1.矿区概述及井田地质特征；2.井田开拓；3.采煤方法及采巷道布置；4.矿井通风；5.矿井安全。

专题部分题目：芦岭矿煤层瓦斯突出的预测与鉴定。采用D、K指数法预测煤层有无突出危险。

翻译部分主要内容为关于减少瓦斯对大气危害的问题，英文题目为：Mitigation of Methane Emissions from Coal Mine Ventilation Air。

ABSTRACT

This design includes of three parts: the general part, special subject part and translated part. The general part is a new design of Luling mine. Luling mine lines in West of huibei in Anhui province. The traffic of road and railway is very convenience to the mine. The run of the minefield is 8.82 km ,the width is about 5.26 km，well farmland total area is 46.39 km2.The eight is the main coal seam, The thickness of the mine is about 9.25m in all. The proved reserves of the minefield are 146.927 million tons. The recoverable reserves are 105.783million tons. The designed productive capacity is 1.2 million tons percent year, and the service life of the mine is 63 years. The normal flow of the mine is 75 m3 percent hour and the max flow of the mine is 120 m3 percent hour. The mineral well gas gushes the deal higher, for high gas mineral well.

The well farmland is a single level in an inclined well to expand.

The working system “four-six” is used in the Sehe mine. It produced 1.20Md/a.

This design includes five chapters: 1.An outline of the mine field geology; 2.development engineering of coalfield; 3.The layout of panels 2.Boundary and the reserves of mine; 4. The ventilation of the mine;5. the safety operation of the mine.

Special subject parts of topics is Forecasting and Identifying of coal and gas outburst. Translation part of main contentses, English topic is: Mitigation of Methane Emissions from Coal Mine Ventilation Air
