【正文】 I 摘 要 本 設(shè)計(jì)礦井為七臺(tái)河精煤集團(tuán)公司新興 一 礦新井設(shè)計(jì) 。 設(shè)計(jì)生產(chǎn)能力為，服務(wù)年限 80a。井田內(nèi)共劃分為 2個(gè)水平開(kāi)采，共有 4 4 450、 5 5 60、 6 6 6 68共 10 層可采煤層 。煤層總厚度為 15m。煤層工業(yè)牌號(hào)為 1/3 焦煤，設(shè)計(jì)井田的可采儲(chǔ)量為 。本礦井設(shè)計(jì)采用雙立井開(kāi)拓方式 ,共六個(gè)采區(qū)，采區(qū)為雙翼開(kāi)采，兩個(gè)工作面達(dá)產(chǎn)。采用煤層群聯(lián)合布置方式， 4 4 49層聯(lián)合開(kāi)采。大巷采用 10t 架線式電機(jī)車(chē)牽引 5t 底卸式礦車(chē)運(yùn)輸， 走向 長(zhǎng)壁采煤法采煤 ， 綜合機(jī)械化回采工藝 ， 頂板處理方法為全部跨落法。 關(guān)鍵詞 : 聯(lián)合開(kāi)采； 可采儲(chǔ)量；開(kāi)拓方式；走向長(zhǎng)壁 ； 全部垮落法 全套圖紙，加 153893706 II Abstract This design is the coal mine of Xin Xing of Qitaihe Coal Mining design production ability is Mt/ longth of service is shaft area totally have two mining levels,there are 44 4 50、 5 5 60、 6 6 6 68 ten coal seams can thickness of the coal seam is seam industry card number is 1/3 coking coal,the recoverable reserves of this shaft area is Mt. This design mine adopt double vertical shaft development as the development way of mine. It have 6 disteicts,each one have two woking faces which can reaches the the union arrangement, 4 4 49 coal seam adopt bine disposal main roadways adopts 10 ton a line type electrical engineering cars lead 5 ton deopbottom mine cars for transport, adopting the longwall coal mining method. Adopting fullmechanized as the mining technology .A plankhandles method as to across to full caving method. Key words: bined disposal； recoverable reserves； development way of mine； long wall coal mining method； full caving method III 目錄 摘 要 .............................................................
