我国于20世纪70年代后期开始采用钢丝绳牵引带式输送机。由于其具有输送距离长、输送能力大、胶带使用寿命长及可运料和乘人的优点,很快在煤炭行业推广。受当时诸多因素制约,这部分设备在设计时仅有制动装置而没有逆止装置,因此一旦制动装置失效就有可能造成重大事故。新版《煤炭安全规程》中明确要求上运带式输送机要同时加装制 In the late 1970s, China began to adopt the wire rope traction belt conveyor. Because of its long transport distance, transport capacity, long service life of the tape and the advantages of materials and passengers, the promotion of the coal industry. Constrained by many factors at the time, this part of the design of the device only the brake device without a check device, so once the brake device failure may result in a major accident. The new version of the “coal safety regulations” clearly required on the conveyor belt conveyor to be installed at the same time
