摘 要
一般部分針對淮南朱集礦井進行了井型為0.9 Mt/a的新井設計。朱集礦井位于安徽省淮南市境內,井田走向長約7.0 km,傾向長約3.0 km,面積約21 km2。主采煤層為13-1#煤層,平均傾角2~5°,平均厚度4 m。井田工業(yè)儲量為113.12 Mt,可采儲量53.09 Mt,礦井服務年限為42.1 a。礦井正常涌水量為342 m3/h,最大涌水量為462 m3/h;礦井相對瓦斯涌出量為10.3 m3/t,屬高瓦斯礦井。
根據井田地質條件,設計采用雙立井單水平開拓方式,井田采用全帶區(qū)式布置方式,共劃分為八個帶區(qū),兩個盤區(qū),軌道大巷、膠帶機大巷和回風大巷皆為巖石大巷,布置在13-1#煤層底板巖層中??紤]到本礦井為高瓦斯礦井,礦井通風方式采用兩翼對角式通風,并在開采前預掘底板瓦斯抽排巷進行瓦斯提前卸壓抽放。
針對東一帶區(qū)采用了帶區(qū)準備方式,共劃分7個分帶工作面,并進行了運煤、通風、運料、排矸、供電系統(tǒng)設計。
針對13101工作面進行了采煤工藝設計。該工作面煤層平均厚度為4.0 m,平均傾角3°,直接頂為泥巖,老頂為細砂巖。工作面采用長壁綜采一次采全高采煤法。采用雙滾筒采煤機割煤,往返一次割兩刀。采用“三八制”工作制度,兩班半生產,半班檢修,截深0.8 m,每天5個循環(huán),循環(huán)進尺4.0 m,月推進度120 m。
大巷采用膠帶輸送機運煤,輔助運輸采用蓄電池式電機車牽引固定箱式礦車。主井采用兩套帶平衡錘的16 t箕斗提煤,副井采用一對1.5 t礦車雙層四車窄罐籠和一個帶平衡錘的1.5 t礦車雙層四車寬罐籠運料和升降人員。
專題部分題目為《國內外無軌膠輪車的運用現狀及發(fā)展趨勢》,結合在神東礦區(qū)、濟三礦的運用,介紹了無軌膠輪車的性能特點,運用現狀,主要車型,以及國產化進程,最后展望無軌膠輪車的發(fā)展趨勢。
翻譯部分題目為《A new coal pillars design method in order to enhance safety of the retreat mining in room and pillars mines》,主要介紹了一種在利用房柱式開采時,可以提高煤柱安全性的煤柱設計方法。

ABSTRACT
The general design is about a 0.9 Mt/a new underground mine design of Zhuji coal mine. Zhuji coal mine is located in Huainan, Anhui province. It’s about 7.0 km on the strike and 3.2 km on the dip, with the 21.0 km2 total horizontal area. The minable coal seam is 13-1# with an average thickness of 4.0 m and an average dip of 3°. The proved reserves of this coal mine are 113.12 Mt and the minable reserves are 53.09 Mt, with a mine life of 42.1 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 13-1# 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.The design applies strip preparation against the first band of East One which divided into 5 stirps totally, and conducted coal conveyance, ventilation, gangue conveyance and electricity designing. The design conducted coal mining technology design against the 13101 face. The coal seam average thickness of this working face is 4.0 m and the average dip is 3°, the immediate roof is mud stone and the main roof is sand stone. The working face applies fully mechanized longwall full-height coal caving method, and uses double drum shearer cutting coal which cuts twice each working cycle. "Three-Eight" working system has been used in this design and the depth-web is 0.8 m with five working cycles per day, and the advance of a working cycle is 4.0 m and the advance is 120 m per month.
Main roadway makes use of belt conveyor to transport coal resource, and battery locomotive to be assistant transport. The main shaft uses double 16 t skips to lift coal with a balance hammer and the auxiliary shaft uses a twins narrow1.5 t four-car double-deck cage and a wide 1.5 t four-car double-deck cage to lift material and personnel transportation.
The project section on "the use of the trackless rubber_tyred car at home and abroad present situation and developing trend", In combination with the application in ShenDong mining area, JiSan Mine, this paper introduces the performance characteristics of trackless rubber_tyred car, using situation, main models, and the localization process and the future development trend of trackless rubber_tyred car.
The title of the translated academic paper is " A new coal pillars design method in order to enhance safety of the retreat mining in room and pillars mines ". Mainly introduces a new type of room and pillar mining, can improve the safety of coal pillar coal pillar design method.
