在矿山废石场溜头的松散碴石堆上,必须装设一座支架作为临时基础,以支承转运设备和碴石的负荷重量。该支架需能随着碴石堆的延伸而周期性地向前搬移,故要求它具有结构简单、搬移方便,工作可靠等特点。目前我国尚无这种定型机构,需要加以解决。我矿在梅坑口的废石场溜头处改革了一种可移式门形支架,经一年多的生产实践,收到了良好的效果,满足了生产的要求。支架的结构见图1。支架的装设见图2。 On a loose ballast pile at the head of a mining wasteland, a stand must be installed as a temporary basis to support the load weight of the transfer equipment and ballast stone. The scaffold needs to be able to move forward periodically with the extension of ballast, so it is required to have the characteristics of simple structure, easy removal and reliable work. At present, there is no such stereotyped institution in our country that needs to be solved. Mine mine in pit mine pithead Mei reform of a removable door-shaped stent, after more than a year of production practice, received good results, to meet the production requirements.
