(畢業(yè)論文專題題目：瓦斯治理新技術(shù)探討)設(shè)計(jì)說明書


摘  要

本設(shè)計(jì)包括三個部分：一般部分、專題部分和翻譯部分。
一般部分為平煤十一礦1.5Mt/a新井設(shè)計(jì)。平煤十一礦位于平頂山礦區(qū)的西南緣，交通便利。主采煤層為二1、四2、五21、五22煤，主要面對二1煤進(jìn)行設(shè)計(jì)。煤層傾角為5.8~34.8 ，平均總厚度為4m。井田地質(zhì)條件較為簡單。
井田工業(yè)儲量為16464萬t，可采儲量為9960萬t。礦井設(shè)計(jì)生產(chǎn)能力為1.5Mt/a，礦井服務(wù)年限為50.1a。礦井正常涌水量為342m3/h，最大涌水量為462m3/h；礦井相對瓦斯涌出量為10.3m3/t，屬高瓦斯礦井。
根據(jù)井田地質(zhì)條件，本設(shè)計(jì)采用雙立井單水平開拓方式，井田采用帶區(qū)式加采區(qū)式布置方式，共劃分為八個帶區(qū)，兩個采區(qū)，軌道大巷、膠帶機(jī)大巷和回風(fēng)大巷皆為巖石大巷，布置在二1#煤層底板巖層中。考慮到本礦井為高瓦斯礦井，礦井通風(fēng)方式采用兩翼對角式通風(fēng)，并在開采前預(yù)掘底板瓦斯抽排巷進(jìn)行瓦斯提前卸壓抽放。
一般部分共包括10章：1、礦區(qū)概述與地質(zhì)特征；2、井田境界和儲量；3、礦井工作制度、設(shè)計(jì)生產(chǎn)能力及服務(wù)年限；4、井田開拓；5、準(zhǔn)備方式——帶區(qū)巷道布置；6、采煤方法； 7、井下運(yùn)輸；8、礦井提升；9、礦井通風(fēng)與安全；10、設(shè)計(jì)礦井基本技術(shù)經(jīng)濟(jì)指標(biāo)。
專題部分題目是平煤十一礦瓦斯治理新技術(shù)，主要是從瓦斯的基本特征、瓦斯抽放技術(shù)及瓦斯監(jiān)測技術(shù)三個方面簡要論述了瓦斯治理新技術(shù)。
翻譯部分主要內(nèi)容是煤與瓦斯突出礦井無人工作面開采保護(hù)煤層的研究，通過理論分析和數(shù)值模擬，設(shè)計(jì)出瓦斯抽放的方案。

關(guān)鍵詞：雙立井；帶區(qū)布置；綜采大采高；兩翼對角式；

 
ABSTRACT

This design includes three parts: the general part, the special subject part and the translation part.
The general design is about a 1.50 Mt/a new underground mine design of Mine Pingdingshan XI. The second, the forth and the fifth are the main coal seams, and its dip angle is 5.8~34.8 degree. The thickness of the mine is about 4m in all. The geologic structure of this coalfield is simple.
The proved reserves of this coal mine are 164.64 Mt and the minable reserves are 99.60Mt, with a mine life of 50.1 a. The normal mine inflow is 342 m3/h and the maximum mine inflow is 462 m3/h. The mine gas emission rate is 10.3 m3/t which can be recognized as high gas mine.
Based on the geological condition of the mine, this design uses a duel-vertical shaft single-level development method, and full strip preparation ,which divided into eight bands and two districts, and track roadway, belt conveyor roadway and return airway are all rock roadways, arranged in the floor rock of the second coal seam. Taking into account of the high gas emission, mine ventilation method use two diagonal wings ventilation, and excaves bottom gas drainage roadway before mining to relief gas pressure in advance.
This design includes ten chapters: 1.An outline of the mine field geology; 2.Boundary and the reserves of mine; 3.The service life and working system of mine; 4.development engineering of coalfield; 5.The layout of panels; 6. The method used in coal mining; 7. Underground transportation of the mine; 8.The lifting of the mine; 9. The ventilation and the safety operation of the mine; 10.The basic economic and technical norms of the designed mine.
The topic of special subject parts is Pingdingshan Coal Mine Gas Control Technology, his paper discusses the application of future development and application. The main shaft skip install skip and the auxiliary shaft install cage. The two wings opposite angles ventilation system is used in the mine.
Translation part is aboat mining the protective seam with the manless working face. Stis shown that the decrease both in operation concentration and the share of pillar mining at deep mines is connected with increasing difficulties in development working support behind the face as well as prevention of roof caving in face area.
Keywords: double vertical shaft; band mode; full-height coal caving; two diagonal wings ventilation
