南屯煤矿在SSP—1000型胶带输送机上采用了HSQ型尼龙芯塑料胶带。经计算,最大张力大致等于容许值,应该不会发生断带事故。但自1983年以来的368天内断带达17次之多,平均21.6天断带一次。为了找出断带原因以利于今后的改进,曾请山东矿院运输机械研究室和力学实验室对胶带性能作了测定。测定证明不是胶带规格上的问题。那么,除维护操作上可能存在问题之外,很可能在机械结构上和技术措施上存在问题,必须对事故原因作出分析和提出改进措施,以保证不再发生频繁断带事故。
Nantun Coal Mine in the SSP-1000 type belt conveyor HSQ-type nylon core plastic tape. After calculation, the maximum tension is roughly equal to the allowable value, should not happen broken belt accident. However, since 1983, 368 days since the break up to 17 times, with an average of 21.6 days broken belt once. In order to find out the reasons for broken belt in order to facilitate future improvements, Shandong Mining Machinery Research Laboratory and Mechanical Laboratory have been asked to measure the tape performance. The test proved not to be a problem on tape specifications. So, in addition to the maintenance operation may be problems, it is likely to have mechanical problems and technical measures, the cause of the accident must be analyzed and proposed improvements to ensure that no frequent frequent accidents.
