摘 要
本畢業(yè)設(shè)計分為三部分：
一般部分針對龐莊煤礦張小樓井進(jìn)行了井型為2.4Mt/a的新井設(shè)計。張小樓礦井位于江蘇徐州市境內(nèi)，井田走向長約4.8km，傾向長約3.53km，面積約16.94km2。主采煤層為7號和9號煤層，上部煤層平均傾角25°，下部煤層平均傾角4°。7號煤層平均厚度10m，9號煤層平均厚度3m。礦井正常涌水量為140m3/h，最大涌水量為160m3/h；礦井相對瓦斯涌出量為6m3/t，絕對瓦斯涌出量為11.32m3/t，屬低瓦斯礦井。
張小樓井田工業(yè)儲量為303.42Mt，可采儲量220.73Mt，礦井設(shè)計生產(chǎn)能力為2.4Mt/a，礦井服務(wù)年限為65.7a。
根據(jù)井田地質(zhì)條件，設(shè)計采用雙立井加暗斜井延伸兩水平開拓方式，第一水平標(biāo)高-600m，采用上下山開采，下上采到-900m，第二水平標(biāo)高為-1130m，-1100m標(biāo)高以上采用上山開采，此標(biāo)高以下采用帶區(qū)開采。井田共劃分為六個采區(qū)，兩個帶區(qū)，軌道大巷和膠帶機(jī)大巷皆為巖石大巷，布置在9號煤層底板巖層中?？紤]到本礦井為低瓦斯礦井，礦井通風(fēng)方式采用中央并列式通風(fēng)。
針對北一采區(qū)采用了采區(qū)準(zhǔn)備方式，共劃分5個工作面，并進(jìn)行了運(yùn)煤、通風(fēng)、運(yùn)料、排矸、供電系統(tǒng)設(shè)計。
針對7101工作面進(jìn)行了采煤工藝設(shè)計。該工作面煤層平均厚度為10.0m，平均傾角25°，直接頂為砂頁巖，老頂為砂巖。工作面采用綜放。采用雙滾筒采煤機(jī)割煤，往返一次割兩刀。采用“三八制”工作制度，截深0.8m，每天四個循環(huán)，循環(huán)進(jìn)尺3.2m，月推進(jìn)度96m。
大巷采用膠帶輸送機(jī)運(yùn)煤，輔助運(yùn)輸采用蓄電池式電機(jī)車牽引固定箱式礦車。主井采用兩對12t長形箕斗提煤，副井采用一對1.5t礦車雙層四車加寬罐籠運(yùn)料和升降人員。
專題部分題目為《張小樓微震規(guī)律分析研究》，以張小樓95206工作面和下山區(qū)域為背景，進(jìn)行了詳實的微震監(jiān)測和數(shù)據(jù)收集與處理，得出了張小樓微震活動規(guī)律，對礦井生產(chǎn)實踐和防治礦井沖擊地壓具有顯著的指導(dǎo)意義。
翻譯部分題目為《WAVEFORM EFFECT ON PRE-AND POST-FATIGUE PROPERTIES OF SANDSTONE》，主要介紹了不同的波形對砂巖疲勞特性的影響。

Abstract
This graduation project is divided into three parts：
The general part in Pangzhuang Coal Mine Well of Zhang well-type 2.4Mt/a Nii design.ZhangXiaolou mine is located in Jiangsu in Xuzhou City, Ida went to the length of about 4.8km, tendency about 3.53km long, with an area of about 16.94km2.The main coal seam No. 7 and No. 9 coal seam, the upper average coal seam dip 25 °, the lower the average coal seam dip angle is 4 °. No. 7 seam average thickness of 10m，No. 9 seam average thickness of 3m. Mine the normal inflow of 140m3 / h , the maximum inflow of 160m3 / h ; mine the relative gas emission in 6m3 / t , is a low - gas coal mine .
Zhang small building Ida Industrial reserves for 303.42Mt , recoverable the reserves 220.73Mt , mine design production capacity of 2.4Mt / a , mine service life of 65.7a .
According to Ida geological conditions , the design uses a dual vertical shaft and the dark inclined to extend the two-level open up the way , the first level of elevation - 600m , down the mountain mining under the mining - 900m , the second level of elevation of - 1130m - 1100m elevation above using the mountain mining, the following bands mining this elevation . Ida total is divided into six mining area , the two bands , track roadway and roadway of the belt conveyor are rock roadway layout in the No. 9 coal seam floor strata . Take into account the mine for the low gas mine , mine ventilation mode with a central parallel ventilation .
Using the mining area to prepare for the North mining area , divided into a total of five face , and coal , ventilation, material transport , to discharge refuse , power supply system design.
In 7101 working face mining technology design.The work face coal seam average thickness of 10.0m, the average angle 25 °, immediate roof for arenaceous shale, sandstone roof.Working face with fully mechanized top coal caving mining.Double drum shearer cutting coal, and a cutting knife two.The "three eight system" working system, cutting depth of 0.8m, every four cycle, cyclic footage of 3.2m, 96m month advance.
Lane using belt conveyor coal, auxiliary transport using battery locomotive traction fixed-box type mine car.Main shaft using two pairs of 12t long skip coal, auxiliary shaft adopts a 1.5T car four car transport material widened double cage and lifting personnel.
Special section entitled "Zhang Xiaolou" by Zhang Xiaolou microseism analysis, 95206 working face for the project as the example, has carried on the detailed micro-seismic monitoring and data collecting and processing, gives Zhang microseismic activity law of mine production practice, and the prevention and control of mine rockburst has significant guiding significance.
Translation part titled "WAVEFORM EFFECT ON PRE-AND POST-FATIGUE PROPERTIES OF SANDSTONE", mainly describes the different waveform on fatigue characteristics of sandstone.
Key words: Zhang mine; mining section layout; double shaft; fully mechanized caving; central parallel; seismic analysis; waveform; rock fatigue
