目前,刮板输送机是采煤工作面及顺槽运输巷的主要运煤设备。但它在生产中存在着重载下难起动的问题,应进一步寻求解决问题的措施。双速电机驱动的刮板输送机就是一个解决起动问题的有效技术途径。
At present, scraper conveyor is the main coal transportation equipment for coal mining face and transportation lane. However, there is a problem that it is difficult to start a heavy load in production. Measures should be further taken to solve the problem.
