随着采煤机械化的发展,使用滚筒采煤机采煤越来越多;况且目前我国使用的滚筒采煤机,多属有链(绳)牵引。但由于管理不善、使用不当,不少局矿发生牵引链(绳)伤人事故较多,给国家和个人造成不可挽回的损失。事故教训应引起有关管理人员、操作人员和接触人员的高度重视,要认真剖析事故、采取有效措施、予以杜绝。 一、事故原因 1.管理不善 ①采煤工作面工况特殊、环境恶劣、且多变性,特别是遇到断层、褶曲、底鼓或顶板下凸煤层变薄等不正常现象,如果管理跟不上,采面工程质量差,运输机就不可能平直,而固定在运输机的机头机尾架上的牵引链(绳)就
With the development of mining mechanization, the use of drum shearer mining more and more; Moreover, the drum shearer used in our country, mostly a chain (rope) traction. However, due to mismanagement and improper use, many accidents involving traction chains (ropes) occurred in the mines, resulting in irreparable losses to the country and individuals. Lessons learned from the accident should arouse the attention of managers, operators and personnel involved. It is necessary to seriously analyze the accident and take effective measures to eliminate it. First, the cause of the accident 1. Poor management ① coal working face special conditions, harsh environment, and variability, especially in the face of faults, fold, bottom drum or roof under the convex seam thinning and other abnormal phenomena, if not with the management On the mining face poor quality, the transport plane can not be straight, and fixed in the nose of the transport aircraft on the tail of the traction chain (rope) on
