General part of the new well design for the XingtaiMine, all articles is divided into ten parts: an overview of mining and geological features, Ida realm and reserves, mine work system, design capacity and service life, Ida development, preparation methods Roadway layout mining methods, underground transport, Mine, mine ventilation and mine safety and design of the main economic and technical indicators. The average strike length of about Xingtai Mine 4892 m, average slope length of about 2698 m, an area of square kilometers. The coal layer within Ida 2 coal, 8 coal thickness were 6m, , the total thickness of , the average angle of 12 degrees. Ida of industrial reserves 108 tons of recoverable reserves of 108 t. Xingtai Mining annual production capacity of million t / a, the service life of 60 years. With shaft (shaft extension) and three levels up the mountain to open up mine used mechanized longwall mining method. Mine layout of a fully mechanized coal face in the whole mine production, the length of 200m, coal transportation in the use of Transport Tunnel belt transport. Mine ventilation with mining area ventilation. Keywords: long wall。 prehensive mechanization。 shaft and three levels up the mountain to open up。 mining area type lley lootive. The ventilation mode of this mine is central unattached mode. Keywords: The strike longwall。 prehensive mechanization。 shaft single level upward and downward development。 central unattached mode 第 頁(yè) 共 120 頁(yè) 7 一 般 部 分 邢臺(tái)礦 240 萬(wàn)噸新井設(shè)計(jì) 第 頁(yè) 共 120 頁(yè) 8 1 礦井概述及井田地質(zhì)特征 礦井概述 礦井位置,范圍 邢臺(tái)礦位于河北省邢臺(tái)市西南部,地理坐標(biāo)為:東經(jīng) 114176。 24′ 15″~ 114176。 30′ 34″ ,北緯 36176。 58′ 31″~ 37176。 03′ 53″,礦區(qū)范圍由以下 29 個(gè)坐標(biāo)拐點(diǎn)圈定,礦區(qū)面積。拐點(diǎn)坐標(biāo)詳見(jiàn)表 11。 表 11 邢臺(tái)礦礦區(qū)范圍坐標(biāo)拐點(diǎn)表 序號(hào) X Y 序號(hào) X Y 1 4094010 38537150 16 4103740 38544545 2 4094480 38538833 17 4103540 38544080 3 4094540 38540335 18 4103155 38543555 4 4094890 38540670 19 4101980 38542190 5 4095400 38540985 20 4102280 38542370 6 4096275 38541310 21 4100730 38540245 7 4096820 38541670 22 4099080 38538980 8 4097730 38541920 23 4099205 38538600 9 4098415 38541950 24 4098730 38538190 10 4098905 38542270 25 4097990 38537815 11 4099485 38542845 26 4097000 38537210 12 4101060 38543340 27 4096330 38536750 13 4101880 38543885 28 4095685 38536535 14 4102690 38544520 32 4093920 38536005 5 4103905 38545305 礦區(qū)東以 F2— 1 斷層為界,南以 F12 斷層為界,西及北以九號(hào)煤層露頭線(xiàn)為界。全礦區(qū)劃分為三個(gè)勘探區(qū):第 I 勘探區(qū):東以 F2 斷層為界,南以地面建筑物保護(hù)煤柱為界,西、北以九號(hào)煤層露頭線(xiàn)為界,面積 ;第 II 勘探區(qū):東以 F F26 斷層為界,南以 F12 斷層為界,北、西以九號(hào)煤層露頭為界,面積 ;第 III 勘探區(qū):東以 F F2— 1 斷層為界,南以 F12 斷層為界,西以 F F26 斷層為界,與第 II 勘探區(qū)相鄰,北以建筑物保護(hù)煤柱線(xiàn)為界,與第 I 勘探區(qū)相鄰
