露天煤矿开采设计方案

摘要本设计为乌兰露天煤矿五采区开采设计，设计生产能力为1.20Mt/a ，矿山服务年限是 13.8年。开采煤层为3-1、4-1、4-2、5-1、6-1 号煤层，开采保有储量为2116.72 万吨，可采储量为 1985.60 万吨。本矿采掘场最终邦坡角为35o，外排土场为22o。本设计包括露天矿开拓系统、采装运输系统及排土系统三大工艺及安全预评价。岩石台阶高度确定为10M，煤台阶为3-1、4-1 号煤的自然厚度。煤、岩台阶的最小工作平盘宽度均为32M。煤、岩的采掘带宽度均为 15M。采用 4 台 KQ-150 型潜孔钻机， 21 台斗容为 2-2.5 型挖掘机， 119 台 BJ-374 型自卸卡车运输， 5 台推土机。评价单元包括采剥系统、边坡、爆破器材、运输、排土系统、总平面布置六个单元。关键词 ：露天开采、爆破、采装、运输、排土、安全预评价Abstract This design for ulam hadad open coal mine mining design, design five mining production ability 1.20 Mt/a, mining and service period is 13.8 years. Mining coal seam for 3-1, 4-1, 4-2, 5-1, 6-no. 1 coal seam mining, the existing reserves for 21.1672 million tons, recoverable reserves of 19.856 million tons. This ore recovery rate is 95%. Mining field slope Angle for the final 35 o, dump outside for 22 o. This design including open-pit mine development system, blasting system, mining outfit in transportation systems and exhaust system process. Four soil Rock the height of steps determined for 10 meters, coal for 3-1 steps, 4-1 the thickness of coal nature. Coal, rock steps of the minimum width are working plates 32 meters. Coal, rock with the mining width are 15 m. 4 sets the type 150 KQ DTH rig,a 21 sets for 2-2.5 let type excavator, 119 "BJ"-374 type dump trucks transport, five units of bulldozers.
