ronment, and always face up to allow Yicha guns of the coal, employees in the work of the safety factor increased substantially. (3) operational safety, workers can significantly reduce the labor intensity, loading feature strong, tracked walking into force, to achieve fullface loading, applicable to all sections of the EOC, ramps roadway construction, the roadway or in the larger crosssection of roadway intersection Construction, we can give full play to the characteristics of its hightech productivity. (4) of the plex, and mobile and applicability, and other equipment in the roadway (such as bolt rig, drilling trucks, scraper conveyor, belt conveyors and mine car) supporting the use of. (5) the use of a machine is ZMC30Hydraulic side dump loaded coal is superior to other types of coal with the main characteristics: 1) available bucket lift heavy objects, such as supporting the use of metal stents, Margaret Fetus. 2) Lifting bucket after supporting the work could serve as platform for roof management. 3) may face shortdistance transportation of materials, such as the backplane, gravel, moving small equipment. 4) for other equipment to provide highpressure pumps, such as hydraulic powered drill bolt. 5) operational safety, can significantly reduce the risk of regional loading operations, moving material time. 6) the local excellent undercover, the performance will help the firstloading operations to achieve 100 per cent of the mechanized so that the noshovel Face really bee a reality. on the existing problems (1) If the loaded coal cars and supporting direct use, will be bucket lift height restrictions, 3 t mine car on the roadway floor flat to a high degree of m, the loaded coal unloading height of m can not be used, To be retargeted. (2) Cable drag protection issues, the aircraft operating in the process of dragging cables, the only person in the plane after a drag, there is no better way. (3) spray sprinklers, in handling the plane, not a random spray sprinkler dust supporting facilities, are currently only artificial rinse dust. (4) with the use of coal in the course of the operation of the plane found that poor people39。 倉(cāng)房開(kāi)采 。針對(duì)各礦在開(kāi)采邊角煤、煤柱時(shí)普遍使用的倉(cāng)房開(kāi)采法的特點(diǎn) , 晉城煤業(yè)集團(tuán)技術(shù)中心根據(jù)現(xiàn)場(chǎng)實(shí)際需要 , 經(jīng)過(guò)調(diào)查研究 , 開(kāi)發(fā)了適用于倉(cāng)房開(kāi)采條件下的可伸縮懸臂式裝煤機(jī) , 以提高倉(cāng)房開(kāi)采的資源回收率 , 減輕工人的勞動(dòng)強(qiáng)度 , 增加現(xiàn)場(chǎng)作業(yè)的安全可靠性。由于三級(jí)臂嵌套于二級(jí)臂內(nèi)、二級(jí)臂嵌套于一級(jí)臂內(nèi) , 在二級(jí)伸縮乳化液缸的作用下 , 懸臂可實(shí)現(xiàn)伸縮動(dòng)作 , 伸縮量為 3 670mm~ 8 270mm。 。耙斗是容積為 的裝煤容器 , 由乳化液絞車拖動(dòng)實(shí)現(xiàn)往復(fù)運(yùn)動(dòng) , 從而完成裝煤機(jī)的裝煤動(dòng)作。軌道行走機(jī)構(gòu)是為便于機(jī)器運(yùn)輸設(shè)計(jì)的 , 適用軌道軌距為 600 mm。行走馬達(dá)通過(guò)一級(jí)齒輪減速 , 將動(dòng)力傳給主動(dòng)輪 , 從而實(shí)現(xiàn)機(jī)器的前進(jìn)、后退。由于裝煤機(jī)在工作時(shí)需由乳化液作動(dòng)力介質(zhì) , 故還需要配備一套乳化液泵站。 可伸 縮懸臂式裝煤機(jī)的井下工業(yè)性試驗(yàn)在晉城煤業(yè)集團(tuán)鳳凰山礦 3314 南回收煤柱放倉(cāng)工作面進(jìn)行 , 煤層厚度 6. 32 m , 容重 1. 5 t246。在開(kāi)幫挑頂爆破后 , 空頂區(qū)堆煤高度可達(dá) 5 m左右 , 幾乎碰著頂板 ??傊?, 機(jī)器運(yùn)行基本達(dá)到了設(shè)計(jì)要求。 4) 機(jī)器結(jié)構(gòu)簡(jiǎn)單 , 操作方便 , 成本低 , 易推廣 。主要技術(shù)參數(shù)如下 : 技術(shù)鏟斗容積 : 。 最大臥底深度 : 600 mm。 額定牽引力 : 20 kN。 系統(tǒng)工作壓力 : 16 MPa。風(fēng)扇電機(jī)功率 : kW。 ZMC 30 型全液壓側(cè)卸式裝煤機(jī)配套設(shè)備的改造 ( 實(shí)現(xiàn)溜子、皮帶“裝載一體化” ) 由于 ZMC 30 型裝煤機(jī)的使用場(chǎng)所在井下 , 空間狹小、受巷道頂板和煤幫所限 , 裝煤機(jī)在裝煤過(guò)程中需用溜子 ( 見(jiàn)圖 1) , 巷道運(yùn)輸使用皮帶 , 溜子每 個(gè)班都要向前移動(dòng)一次。 圖 1 ZMC 30 側(cè)卸式裝煤機(jī)的優(yōu)點(diǎn) (1) 通風(fēng)良好 , 主要表現(xiàn)在風(fēng)筒不易被煤擠壓 , 掉落 , 始終保持風(fēng)流正常 , 瓦斯不超限。 (5) 一機(jī)多用是 ZMC 30 型全液壓側(cè)卸式裝煤機(jī)優(yōu)于其他類型裝煤機(jī)的主要特點(diǎn) : 1) 可用鏟斗舉升重物 , 如支護(hù)用的金屬支架、碹胎。 5) 作業(yè)安全 , 可顯著減少在危險(xiǎn)區(qū)內(nèi)的裝載作業(yè) , 搬動(dòng)物料時(shí)間。 (3) 噴霧灑水 , 該機(jī)在裝卸時(shí) , 沒(méi)有隨機(jī)配套的噴霧灑水防塵設(shè)施 , 目前只能人工沖洗
