CATERPILLAR will supply a complete longwall top coal caving (LTCC) armoured face conveyor system to Datong Coal Mine Group’s Majialiang coal mine. It will be the fifth set of Cat LTCC face conveyors delivered to the mine, which is near Datong City in Shanxi Province.

Cat conveyor with LTCC roof supports

A Cat conveyor and longwall top coal caving (LTCC) roof supports. A complete Cat LTCC face armoured conveyor system will be delivered to Majialiang coal mine in Shanxi Province.

In the LTCC arrangement, the armoured face conveyor (AFC) system has one conveyor in front of the roof supports to move coal cut from the face and one conveyor behind the roof supports to move caved coal.

Both the front face conveyor and the rear face conveyor will be about 250 metres in length, and each will have a 2 x 1050 kW drive system. The beam stage loader will be approximately 50 metres in length with a 1 x 600 kW drive system.

The world-class LTCC coal mining operation has a seam height of 6.32 metres on average, and the working face is approximately 250 metres. Production capacity is as much as 40,000 tonnes per day.

This new contract is the 22nd LTCC face conveyor contract signed by Caterpillar and Datong Coal Mine Group since 2004.

The Caterpillar underground product group in Luenen, Germany, specifically designed this newest system to meet the production and service life requirements of the Majialiang mine.

The Luenen facility will supply the drive systems for the AFC and stageloader, the crusher, belt return unit and the control system. The Caterpillar Langfang facility in China will manufacture the conveyor pans and drive frame structures.

This contract marks the first complete LTCC conveyor structure to be manufactured in the Langfang facility.

Surface commissioning of the entire system was started at Majialiang mine in April and the longwall is expected to be fully operational underground during the second quarter of 2017.

Datong Coal Mine Group is the third-largest state-owned coal mining enterprise in China, after Shenhua Group and China Coal Group. Its coal mines are in Shanxi Province and adjoining Inner Mongolia Autonomous Region.

Datong has a long history of coal mining dating back to the end of the Ming Dynasty and start of the Qing Dynasty. During the past 62 years it has produced more than 2.1 billion tonnes of coal.


大同煤业集团的新型Cat长壁刮板输送机

卡特彼勒采矿设备有限公司将向大同煤业集团下属的麻家梁煤矿交付一套用于长壁综放开采(LTCC)的刮板输送系统。这将是这家位于山西省大同市附近的煤矿采购的第5CatLTCC刮板输送系统。

LTCC的设计中,刮板输送系统(AFC)在顶部支架前有一台输送机用于运送从工作面切下的煤,在顶部支架后有一台输送机用于运送落下的煤。

前部和尾部的刮板输送机都长约250米,各配有2x1050千瓦的传动系统。皮带卸料机长约50米,配有1x600千瓦的传动系统。

这一世界级的LTCC设备的平均焊缝高度为6.32米,工作面高度为约250米。开采能力可达每天40,000吨。

该笔合同是卡特彼勒与大同煤业集团字2004年以来签署的第22LTCC刮板运输机采购合同。

位于德国吕嫩市的卡特彼勒采矿设备集团为了符合麻家梁煤矿的生产和使用寿命要求专门设计了这一最新的系统。

吕嫩工厂将为刮板运输机(AFC)、皮带卸料机、破碎机、皮带回路部件以及控制系统提供传动系统。卡特彼勒位于中国廊坊的工厂将生产输送机盘和传动主体结构。

这一合同也标志着廊坊工厂生产的第一套完整的LTCC输送机主体结构。

整套系统的井上调试于4月在麻家梁煤矿启动,预计在20172季度实现井下全面运转。

大同煤业集团是中国第3大国有煤炭生产企业,紧随神华集团和中煤集团之后。其下属煤矿位于山西及与内蒙古自治区交界处。

大同的采煤历史可以追溯到明末清初。在过去的62年中,该市的煤产量超过21亿吨。
