安源實業(yè)有限公司五方井礦井初步設(shè)計設(shè)計說明書

摘要:  設(shè)計根據(jù)五方井礦的煤層賦存情況、地質(zhì)構(gòu)造、水文特征、以及地面交通等條件對礦井的開拓方案進(jìn)行了經(jīng)濟(jì)技術(shù)比較，最后確定了以平硐、立井的綜合開拓方式。設(shè)計本著“安全第一，效益第二”的原則對礦井的開拓、經(jīng)營以及管理各方面進(jìn)行了分析和論證。根據(jù)煤層的厚度和實際賦存情況井田內(nèi)地質(zhì)構(gòu)造比較簡單，屬低瓦斯礦井，本井田主要可采煤層有三層，煤層傾角平均18o，屬于緩傾斜煤層，設(shè)計采用單一走向長壁采煤法。為響應(yīng)用我國當(dāng)前采煤方法的發(fā)展方向,本礦井設(shè)計采用綜合機(jī)械化沿空留巷采煤工藝,對于下部厚煤層采用綜采放頂煤技術(shù)，礦井初步設(shè)計生產(chǎn)能力為120萬t/a，服務(wù)年限為89年.對于安全方面，本礦井為低瓦斯礦井，但為確保安全特設(shè)置瓦斯監(jiān)控系統(tǒng)。

Preliminary design of the five fang Colliery

Abstract: According to the design of the five parties mining coal storage wells, geological structure, hydrological features, as well as ground transportation, and other conditions on the mine's development programme for the economic and technical comparison, the final determination to Adit, the shaft develop a comprehensive manner. Design of "safety first, the second-effectiveness" of the principle of mine development, operation and management of all aspects of the analysis and feasibility studies. According to the seam thickness and the actual occurrence in the mine field geological structure is relatively simple, a low-gas coal mine, the mine field of the major coal mining can have three levels, the average coal seam dip 18 , gently inclined coal, designed with a single to long wall mining . In response to China's current mining method direction for the development of an integrated design of the mine along the goaf mechanized coal mining technology, the lower part of a thick coal seam Fully-caving, mine preliminary design production capacity of 1.2 million t / a, Length of service for 89. For safety, the mine for the low-gas coal mine, but to ensure the safety of gas set up special monitoring system

Key words: adit cut mining;  shaft development;the method of combined development; compr ehensive mechanized coal mining;technology of fully mechanized mining with top-coal drawing in thick coal seams: single longwall mining on the strike;maitaining entries along gob edges;
