【正文】 ty of 2 million tons of ore limestone mine open pit design, the main purpose of the design is based on the requirements for the rational design of Shangyang limestone mining methods and develop solutions . The main idea is designed by the known Daejeon Ottawa County town Shangyang limestone relevant information, in accordance with relevant state regulations, based on what they have learned during college , and with reference to the status of mining mines abroad selection of similar size and determine the appropriate mining parameters to design according to the requirements set out on economically reasonable and technically feasible with the actual situation conducive to the exploitation of the optimal solution. The content design include:determining mining overview, technical and economic parison study geological characteristics of the deposit,the determination of the realm of openpit mining , mine development and transportation design, selection of mining machinery and mining equipment , the overall layout of the mine , mine support facilities , environmental protection and occupational safety and health , mine mine to determine the amount of civil works , mainly in the realm of openpit mining determined to open up the selection of transport mine design, mining machinery and mining equipment based. The main parameters of this design has a designed annual production capacity of 200 million tons of ore . Design economical stripping ratio of 179。, pioneering the way for the road transport development, bench slope angle of 70 176。, the step height of 10m。 outdoor mine minimum bottom width of 25m, the ultimate exploitation of the bottom elevation of +360 m. Within the realm of open pit mineable reserves of 72,692,000 tons , recoverable life of years . Transport equipment for the SH380 type dump truck and WK4 type shovel . Balanced stripping ratio of / t. Designed with KQ250 type submersible drilling rig piercing , slash detonate . Using motor transport Dump Dump machine . 武漢科技大學本科畢業(yè)設(shè)計 III Keywords: limestone of Shangyang。 economical stripping ratio。 slash initiation 武漢科技大學本科畢業(yè)設(shè)計 IV 目 錄 1 總論 ...................................................................................................................................... 1 礦區(qū)簡介 .................................................................................................................... 1 設(shè)計 依據(jù)及設(shè)計原則 ................................................................................................ 1 設(shè)計對象 .......................................................................................................... 1 設(shè)計依據(jù) .......................................................................................................... 1 設(shè)計原則 .......................................................................................................... 1 主要設(shè)計內(nèi)容 ............................................................................................................ 2 2 經(jīng)濟部分 .............................................................................................................................. 3 勞動定員和勞動生產(chǎn)率 ............................................................................................ 3 基本建設(shè)投資 ............................................................................................................ 4 建設(shè)工程費 ...................................................................................................... 4 生產(chǎn)成本費 ...................................................................................................... 4 設(shè)備購置費 ...................................................................................................... 4 生產(chǎn)技術(shù)建筑費 .............................................................................................. 4 職工生活福利設(shè)施投資費用 .......................................................................... 4 其他費用 .......................................................................................................... 4 露天礦主要技術(shù)經(jīng)濟指標 ........................................................................................ 4 3 地質(zhì)部分 .............................................................................................................................. 6 地形地貌 .................................................................................................................... 6 經(jīng)濟狀況 .................................................................................................................... 6 氣候 ............................................................................................................................ 6 區(qū)域地質(zhì)概況 ............................................................................................................ 6 地層 .................................................................................................................. 6 構(gòu)造 .................................................................................................................. 7 侵入巖 .............................................................................................................. 8 圍巖蝕變 .......................................................................................................... 8 礦產(chǎn) .................................................................................................................. 8 礦段地質(zhì) .................................................................................................................... 9 地層 .................................................................................................................. 9 構(gòu)造 ................................................................................................................ 10 侵入巖 ............................................................................................................ 11 圍巖蝕變 ....
