en.Wedoany.com Reported - Recently, the Hulusu Coal Mine of Zhongtian Hechuang Energy Co., Ltd., located in Wushen Banner, Ordos City, Inner Mongolia Autonomous Region, China, completed the installation and commissioning of a new adjustable belt conveyor turning device in its main haulage roadway of the sixth mining area, which has been put into normal operation. The device features horizontal turning, vertical turning, combined turning, and slope-changing capabilities, equipped with a belt-pressing and anti-floating mechanism. It aims to address common faults such as belt floating, misalignment, and material spillage during belt transportation in complex working conditions like curved roadways, fault zones, and short-distance crosscuts, thereby enhancing the mine's continuous transportation capacity and system stability.
Zhongtian Hechuang Energy Co., Ltd., established in 2007, is jointly funded by four shareholders: China Coal Energy Co., Ltd., Sinopec Great Wall Energy & Chemical Co., Ltd., Shanghai Shenergy Co., Ltd., and Inner Mongolia Manshi Coal Group Co., Ltd. The Hulusu Coal Mine is one of the company's core mines, with a designed annual production capacity of 13 million tons, making it a large modern underground mine in China. Traditional belt conveyors, limited by their structure, often require multiple equipment connections or the use of scraper transfer machines in complex roadways, leading to high equipment investment, energy consumption, increased costs for electrical control systems and chamber development, as well as frequent issues like belt floating and misalignment, which hinder tunneling progress.
The newly deployed turning device enables a single unit to adapt to various complex transportation scenarios. In curved roadways, it can completely replace the mode of multiple conveyor connections and scraper transfer, streamlining transfer points and saving equipment and power consumption. In tunneling faces, the tail of the device can be directly extended to the excavation head, eliminating the processes of laying, assembling, disassembling, and transferring scrapers, reducing labor input and intensity. In short-distance crosscut transportation scenarios, the head, belt storage, and tensioning devices can be shared before and after the turn, with a minimum layout distance of only 3 meters from the tail to the turning section, solving the problem of limited conveyor layout space and frequent scraper replacement during the final mining phase. In fault zones, the belt-pressing mechanism eliminates the safety hazard of belt floating, enabling continuous transportation through fault zones with a single conveyor.
According to information released by the Hulusu Coal Mine, the implementation of this device has effectively improved the stability of belt transportation under complex underground roadway conditions, reducing equipment failure rates and maintenance workloads, and providing technical support for intensive and efficient mine transportation. In the next step, the mine plans to continue promoting the innovative application of intelligent and intensive mining technologies, and to promote new process equipment to enhance safety production and transportation efficiency.
