变化管理下的“撑杆跳”

近年来,山东能源枣矿集团新安煤业公司坚持系统化管理思维,找准矿井集约发展路径,稳步推进实施“两减两优”,减头、减面,优化系统、优化劳动组织,促进了增值开采。

优化采场布局

“我们积极调整采区开拓施工方案,暂停3上305面掘进施工,把重点接续工作面3311面材料巷调整为大采高施工,对切眼进行刷大,运输巷全线挑顶,集中优势兵力加快采区准备。”新煤公司经理张延伟说。公司加大对开拓设计的优化调整力度,采取灵活多变的工作面布置方式,以实现增加可采储量和减头减面减成本的目标。

新煤重点实施了3405面系统改造和设备更换方案,延长工作面服务年限3个月,而且多回收煤炭资源近50万吨;3下209工作面材料巷实施支护改革,较新掘巷道节约材料及人工费用100余万元,多回收煤柱资源1万多吨,创效350余万元;优化了矿井南翼回风联络巷的施工方案,将南翼回风巷上段与-392胶带联络巷共用,满足了34、32采区边角煤柱的开采使用,实现了“一巷多用”。

“我们曾受头多、面多、人少之累。‘两减两优’之后,实现了减面提效,初步形成了‘两主一辅’三面高效集约化生产格局。”张延伟说。

推进“储装运”一体化改造

日前,新煤公司-300集中2#煤仓投入使用,增加仓储量近4000吨,为年底取消采煤夜班生产创造了条件。这是该公司稳步推进井下“储装运”系统一体化升级改造的一个缩影。

同时,新煤从提升装备水平及产能入手,在3406工作面使用了郑煤集团生产的ZT9000型支架以及净化水装置、永磁电机等先进设备,实现了远距离供液、供电、软化水直供。为了发挥大储量、厚煤层、大采高的资源优势,3113工作面采取“大系统、大生产”布局,装备一套全省最高的6.5米大采高综采成套设备。届时,如正常开采,一个面一天产量可达1.5万吨以上,工效提升120%以上。

为满足大生产的需求,与之相适应增加主运皮带运输能力,将井下集中三部强力皮带机控制方式由“高压起动器 电机 CST”改造为“变频器 永磁电机 快速联轴器”,皮带机带速可提高至4.5米/秒,每小时可增加煤炭运量300吨,机电事故率下降60%,电耗降低20%。

该公司还致力于矿井供电、提升、通风、运输、排水等生产系统自动化集中控制改造,逐步实现井下排水、变电所、地面压风机等固定设备场所远程监控和无人值守,减少岗位人员。

“我们不再走上人员、拼产量的老路,坚持效率优先原则,深入研究高效生产组织方式,大力度推进机械化换人、自动化减人,努力实现安全均衡高效生产。”张延伟表示。
