煤矿排矸系统改造方案煤矿排矸系统改造方案 我矿排矸系统设备陈旧 目前仍使用老式前倾式翻车装置 自制 轻 重车线设置不尽合理 矸石山下车场只能存放 5 辆车 轻 重车线重 合段太长 空车存放车场小 造成排矸效率低下 排矸时每次只能拉五辆 车 一次循环时间达 20 25min 每天的理论排矸能力为 288 360 车 我矿东翼轨道巷和西翼轨道巷的断面积均为 19 97m2 每米矸石量大 约 46 车 按每个掘进头每天 2m 进尺计算 每天的出矸量为 184 车 西翼 回风巷的断面积均为 22 25m2 每米矸石量大约 50 车 按每天 2m 进尺计 算 每天的出矸量为 100 车 东翼回风巷和 2104 联络巷的断面积均为 22 25m2 每米矸石量大约 50 车 按每天 2m 进尺计算 经带式输送机进 入选矸系统 出矸石率按三分之二考虑 每天的出矸量为 66 车 2103 综 采工作面长 170m 按 0 3m 高为矸石计算 选矸量大约每天 120 车 矿井 每天的总排矸量为 470 车 所以 正常生产 暂按一个采煤工作面 五个 开拓掘进头计算 后 排矸能力严重不足 为满足正常生产后对排矸能力 的要求 亟需对现有排矸系统进行更新改造 一 系统一 系统改造的技术原则改造的技术原则 1 采用先进而且应用成熟的技术 2 保证整个系统安全可靠 3 能实现连续作业 二 系统改造方案对比二

矸石落入矸石仓 用带式 输送机将矸石运至矸石山 同时将现矸石山场地平整后建造环形车场 并 与现有空车线连通 增加空车存放位置 方案二 在绞车房东南角处新建翻滚笼排矸系统 利用工区办公室门 前的轨道 将矸石车牵引至翻滚笼处 矸石翻入矸石仓 再用仓下带式输 送机和矸石山带式输送机运送至矸石山 此方案的优点是 轻 重车线 互不干扰 可利用蓄电池电机车将矸石车推至翻滚笼 减少了调度绞车 运输的环节 缺点是 离提升机房太近 噪声和粉尘污染大 未彻底 解决空车存车场小的问题 因场地原因 带式输送机走廊建设较困难 通过副井提升上来的煤车无法翻车 翻车机房挡住了去主通风机房的 车辆行驶道路 方案三 在原瓦斯抽放泵站前现矸石山下车场位置新建翻滚笼排矸系 统 矸石仓下安装一套 2 2m3三面翻矸翻车系统 直接翻矸 此方案的优 点是 离工作生活区较远 污染小 一定程度上提高了排矸效率 缺 点是 翻矸后空车需走回头路 与重车线路相抵 未彻底解决轻 重车 循环问题 施工土建工程量较大 需要再安装一台 1 2m 或 1 6m 翻矸 绞车 投资较大 需更换翻矸架 经过方案论证对比 推荐使用第一方案 经过方案论证对比 推荐使用第一方案 该方案的主要特点 以一台 液压站作为整套翻车设备的动力源 把以往电动 电液相混杂使用变为单 一的液压驱动 液压站采用双电机双液压泵的液压驱动系统 其中一台工 作
