As we all know, underground mining is basically a harsh and complex mining environment in mine production. In addition to the characteristics of ruggedness and long service life, the models that can be used in the underground mining production environment need more flexible performance, convenient maintenance and higher production efficiency.

與其他裝載機(jī)相機(jī)，井下裝載機(jī)的裝載容量顯著提升，挖掘性能增強(qiáng)，坡道速度更快，前車架強(qiáng)度更高，并且配備“減少通風(fēng)套件”以降低機(jī)器和礦場運(yùn)營成本，其中包括佳的操作員性和舒適性、經(jīng)過實(shí)地驗(yàn)證的動力傳動系和緊湊的外形。

Compared with other loader cameras, the underground loader has significantly improved loading capacity, enhanced excavation performance, faster ramp speed, higher front frame strength, and is equipped with a "reduced ventilation kit" to reduce machine and mine operating costs, including good operator safety and comfort, field proven power train and compact shape.

目標(biāo)：提高生產(chǎn)效率

Objective: improve production efficiency

井下礦用裝載機(jī)是專為額定有用負(fù)載22t的裝載—運(yùn)輸和卡車裝載應(yīng)用而設(shè)計(jì)。由于容量增大，此新型裝載機(jī)可以為新型井下鉸接式卡車提供嚴(yán)格的三趟次匹配能力。

Underground mine loaders are designed for loading transportation and truck loading applications with a rated useful load of 22T. Due to the increased capacity, the new loader can provide strict three times matching capacity for the new underground articulated truck.

加大的提升油缸經(jīng)過重新定位能夠提供更大的提升力，而加大的傾斜油缸則能夠提供更具侵入性的挖掘特點(diǎn)，從而提高有用載荷容量。此外，重新設(shè)計(jì)的扭矩管（位于實(shí)心鋼提升臂之間）和新型鏟斗限位器（用于減少鏟斗回拉時(shí)的應(yīng)力）共同作用，可以提高前連桿的強(qiáng)度和耐用性。

The enlarged lift cylinder can provide greater lifting force after repositioning, while the enlarged tilt cylinder can provide more invasive excavation characteristics, so as to improve the useful load capacity. In addition, the redesigned torque tube (located between solid steel lifting arms) and the new bucket stopper (used to reduce the stress during bucket pullback) can improve the strength and durability of the front link.

井下礦用裝載機(jī)傳動系中的新型鎖止式離合器變矩器可顯著提高坡道上的驅(qū)動行駛速度。此速度的提高使上坡裝載–運(yùn)輸應(yīng)用的生產(chǎn)效率得以改善。

The new lock up clutch torque converter in the transmission system of underground mine loader can significantly improve the driving speed on the ramp. This increase in speed improves the productivity of uphill loading transport applications.

優(yōu)點(diǎn)：減少通風(fēng)套件

Advantages: reduced ventilation Kit

在很多井工礦，人們非常注意減少移動設(shè)備柴油機(jī)廢氣中的顆粒物（PM）排放。人們小心謹(jǐn)慎地調(diào)節(jié)井下環(huán)境中的PM水平，而保持礦井充分通風(fēng)、控制井下空氣質(zhì)量的費(fèi)用可能在礦場的運(yùn)營成本中占很大比重。

In many mines, people pay great attention to reducing particulate matter (PM) emissions from diesel engine exhaust of mobile equipment. People carefully adjust the PM level in the underground environment, and the cost of maintaining sufficient ventilation and controlling underground air quality may account for a large proportion of the operation cost of the mine.

為這個(gè)問題，山汽集團(tuán)采用特定的發(fā)動機(jī)硬件和軟件修改以大限度地減少PM排放。井下礦用裝載機(jī)對通風(fēng)的要求降低了42%。除了限度地減少PM以外，還可以降低燃油消耗量并且提高雙失速輪緣牽引力，從而提高機(jī)器性能。

In order to solve this problem, Shanqi group adopts specific engine hardware and software modifications to greatly reduce PM emissions. The ventilation requirements of underground mine loaders have been reduced by 42%. In addition to minimizing PM, it can also reduce fuel consumption and improve double stall rim traction, so as to improve machine performance.
