The length of mining conveyor belts, especially coal mine conveyor belts, can reach a considerable distance. The following is a detailed analysis of the longest length of the mine conveyor belt:
1、 Longest length record
In practical applications, the length of a single conveyor belt is generally between several hundred meters and one kilometer. However, in some special or advanced coal mines, the length of a single conveyor belt can reach very long distances. For example, Huayin (Xingren) Coal Company, located in Yinchuan, Ningxia, China, has adopted a coal mine conveyor belt with a single machine length of 11.8 kilometers, setting a record for the longest single machine conveying distance of similar equipment in the world.
In addition, there is information indicating that the maximum length of a single coal mine conveyor belt can reach about 12 kilometers, but there are also certain technical challenges in manufacturing and installing such ultra long conveyor belts.
2、 Factors affecting length
Production demand: The production scale, output, and properties of the conveyed materials in the mine will directly affect the length design of the conveyor belt.
Equipment investment: A longer conveyor belt means higher equipment investment, including the cost of the conveyor belt itself, driving devices, support structures, etc.
Maintenance cost: The maintenance and management of long conveyor belts are relatively complex, requiring more maintenance personnel and more frequent maintenance operations.
Technical limitations: The length of the conveyor belt is limited by factors such as material strength, manufacturing process, and driving technology.
3、 Length characteristics of different types of conveyor belts
Groove belt conveyor: The length can reach over 500 meters, and the length of the curved belt conveyor used in mines may reach up to 1km. The tilt angle should be controlled within 30 degrees.
Large angle belt conveyor: The length is usually controlled within 80 meters, as the skirt conveyor belt should not be too long. But its tilt angle can reach 90 degrees, achieving vertical lifting.
In summary, the length of mining conveyor belts can reach a considerable distance, with the longest record exceeding 11 kilometers. However, the specific length still needs to be comprehensively considered based on factors such as the production needs of the mine, equipment investment, maintenance costs, and technical limitations.
矿山输送带，特别是煤矿传送带单机的长度，可以达到相当长的距离。以下是对矿山输送带最长长度的详细分析：
一、最长长度记录
- 实际应用中，传送带单机的长度一般在几百米到一千米之间。然而，在一些特殊或先进的煤矿中，传送带单机的长度可以达到非常长的距离。例如，在中国宁夏银川建设的华银（兴仁）煤炭公司，其采用的煤矿传送带单机长度达到了11.8公里，这一长度创造了全球同类设备最长单机输送距离纪录。
- 另外，有信息表明煤矿传送带单机最长可以达到12公里左右，但制造和安装这种超长传送带也存在一定的技术挑战。
二、影响长度的因素
- 生产需求：矿山的生产规模、产量以及输送物料的性质都会直接影响输送带的长度设计。
- 设备投资：更长的输送带意味着更高的设备投资，包括输送带本身的成本、驱动装置、支撑结构等。
- 维护成本：长输送带的维护和管理相对复杂，需要更多的维护人员和更频繁的维护操作。
- 技术限制：输送带的长度受到材料强度、制造工艺、驱动技术等方面的限制。
三、不同类型输送带的长度特点
- 槽型皮带机：长度可达500米以上，矿山用拐弯皮带输送机长度可能达到1km。倾斜角度需控制在30度以内。
- 大倾角皮带机：长度通常控制在80米以内，因为裙边输送带不宜过长。但其倾斜角度可达90度，实现垂直提升。
综上所述，矿山输送带的长度可以达到相当长的距离，最长记录已超过11公里。然而，具体长度还需根据矿山的生产需求、设备投资、维护成本和技术限制等因素综合考虑。
