在杰兹卡兹甘采矿冶金联合企业的矿山,盘区-柱式开采法的回采过程包括下列依次完成的工作面作业:钻炮眼、炮眼装药和爆破,矿岩装载,钻锚杆支护孔,顶板支护。各项作业之间的间歇宜缩短到规定的极限,这个极限就是设备利用率开始下降的采矿作业集中程度。编制计划的任务是保证自行设备和回采工作线得到合理利用。按照现行的计算流程,炮眼崩矿的回采工作计划是分两阶段编制的。第一阶段,根
At the Mining, Metallurgical Complex of the Jezazagzgan Mining and Metallurgical Complex, the recovery process of the panel-pillared mining method includes the following face-to-face operations: drilling blasthole, blasthole charge and blasting, rock loading, bolting bolting Hole, roof support. The interval between operations should be shortened to the required limit, the limit is the concentration of mining operations began to decline in equipment utilization. The task of preparing a plan is to ensure that its own equipment and mining lines are used wisely. According to the current calculation process, the blasting mine blasting work plan is prepared in two phases. The first stage, root
