现代化矿井煤炭运输普遍使用带式输送机,而且朝集中控制和地面控制方向发展。但在运输过程中不可避免地存在底带回煤,使机尾处积煤的问题。使设备不能正常运转,有时还能造成重大事故。要解决这一问题,除了从根源上减少底带回煤外,在机尾采取保护措施是非常必要的。 Modern mine coal conveyor belt conveyor is generally used, but also toward centralized control and ground control direction. However, in the course of transportation, there is inevitably the problem of bottom coal returning and coal accumulation at the tail end. So that equipment does not work, and sometimes can cause major accidents. To solve this problem, in addition to reducing the backfill from the root cause of the coal, the protection measures taken at the tail are very necessary.
