在采煤工作面的生产过程中,为保证工人的安全和各项工作的正常进行,必须对顶板进行控制。在顶板控制过程中,放顶是对工人安全威胁最大的一个环节。近年来由于放顶支架的应用,实现了工作面放顶移溜机械化。下面将我局引进苏联的“卫星”型放顶支架的控顶特点及其在我局埠村煤矿的使用情况作简要的介绍。 一、“卫星”型放顶支架的适用条件及主要技术参数
In the coal mining face during the production process, in order to ensure the safety of workers and all the normal work, we must control the roof. Roof control is a major threat to workers’ safety during roof control. In recent years due to the application of roof caving, roof mechanization has been achieved. The following will be my bureau to introduce the Soviet Union’s “satellite” type roof support top control features and its use in port I Bucun coal mine for a brief introduction. First, the “satellite” type roof placement bracket for the application of the conditions and the main technical parameters
