Summary of the mine, this chapter mainly introduces the position, geology and conditions of the coal seam. 2. Mine development. This chapter extrapolates among other areas, reserve, serving limits, working system, spot of the draft, selection of level, further drift of mine, panel division a nd underground station. of mining districts and retreating technology. This chapter explains the general situation of the mining district, technology and techniques of the working face, roadway layout and operation system in the mining district, the design of the mining district station, cave layout and the schedule for drainage and mining in the main mining district. system of the mine, this chapter states transportation, haulage, ventilation and drainage systems of the mine and the selection of equipment used in the system mentioned above. In order to practice and reinforce the wealth of the knowledge learned in the past four years, I try my best to introduce various stateofthearts when respecting the specific situation of Beipang coal mine. For instance, long wall mine on the inclination, long wall mining on the strike with top coal drawing, and among others, drifting and retaining gateways along goaf are preferred in the design. In addition, the design connects operational situation of a mine with a college student’s ability to elementary scientific research. What’s more, it has been pleted with the aid of AutoCAD2020, which streamlined the design process dramatically and lessened the hardness of drawing significantly. 4 目 錄 第一章 礦區(qū)概述及井田特征 ...........................................................1 第 節(jié) 礦區(qū)概述 ........................................................................... 1 井田地理位置與交通條件 ............................................. 1 第 節(jié) 井田地質(zhì)特征 ..................................................................... 2 地質(zhì)特征 ......................................................................... 2 地質(zhì)構(gòu)造 ......................................................................... 3 水文地質(zhì) ......................................................................... 3 第 節(jié) 煤層特征 .............................................................................. 4 煤層 .................................................................................. 4 含煤性概述 ..................................................................... 4 煤層分述 ......................................................................... 4 井田煤質(zhì)特征 ................................................................. 5 可采煤層的煤質(zhì)指標(biāo)特征 ............................................ 5 第二章 井田境界及儲量 .....................................................................7 第 節(jié) 井田境界 .............................................................................. 7 第 節(jié) 井田工業(yè)儲量 ..................................................................... 7 第 節(jié) 井田可采儲量 ..................................................................... 8 井田煤柱留設(shè) ................................................................. 8 可采儲量計(jì)算 ................................................................. 9 第三章 礦井生產(chǎn)能力、服務(wù)年限及工作制度 ..............................10 5 第 節(jié) 礦井生產(chǎn)能力及服務(wù)年限 .............................................. 10 第 節(jié) 礦井工作制度 .................................................................. 10 第四章 井田開拓 ................................................................................ 11 第 節(jié) 概述 .....................................................................................11 地質(zhì)構(gòu)造 ........................................................................11 煤層賦存狀況 ................................................................11 水文地質(zhì)情況 ................................................................11 第 節(jié) 開拓方式的確定 ............................................................... 12 定井筒形式、位置、數(shù)目 ........................................... 12 開拓方案技術(shù)比 較 ....................................................... 15 井筒位置的確定 ........................................................... 18 第 節(jié) 開采水平的設(shè)計(jì) ............................................................... 22 水平高度的確定應(yīng)考慮如下因素 .............................. 22 確定開采設(shè)計(jì)的較優(yōu)方案 .......................................... 24 設(shè)計(jì)水平的巷道布置 .................................................. 24 第 節(jié) 井底車場 ............................................................................ 26 車場內(nèi)各種存車線長度計(jì)算 ...................................... 26 井底車場的調(diào)車方式 ................................................ 29 井底車場的通過能力計(jì)算 .......................................... 30 井底車場各硐室布置 .................................................. 32 第五章 采煤方法和帶區(qū)巷道布置 ...................................................35 第 節(jié) 煤層的地質(zhì)特征 ............................................................... 35 6 煤層埋藏條件 ............................................................... 35 煤質(zhì)與地質(zhì)情況 ........................................................... 35 采煤方法及其機(jī)械化程度的確定 .............................. 35 回采工作面參數(shù)的確定 ............................................... 36 回采工作面破煤、裝煤方式的確定 .......................... 37 采煤機(jī)的工作方式 ....................................................... 38 回采工藝 ..................................................
