立井开拓是目前地下矿山开拓的主要方式之一,立井井筒施工时采用混凝土支护,混凝土送到支护工作面的容器主要采用的是灰罐(底卸式吊筒)。利用灰罐的混凝土浇筑过程中,灰罐到达井口后摘罐放到平板车上,人工推罐到搅拌机下方接入混凝土,然后推回井口,挂罐稳罐后送入井下。在此过程中,摘罐、推罐、挂罐、稳罐存在不安全因素,灰罐从上井、装罐到下井的时间偏长。利用混凝土入罐皮带机将混凝土输送到灰罐中,可有效避免以上的不安全因素,节省人力,降低工人的劳动强度,且操作简单,维修量小,值得推广应用。 Shaft development is currently one of the main ways to open up underground mines. The use of concrete support for shaft construction in vertical shafts and the use of gray cans (bottom discharge type) for containers delivered to the support face by concrete. In the process of pouring the concrete with the gray tank, the gray tank reaches the wellhead and picks the tank onto the flatbed truck. The tank is manually pushed into the concrete to be mixed with the concrete and then pushed back to the wellhead. During this process, unscrupulous factors such as picking, pushing, hanging, and stabilizing the tank exist, and the time for the gray tank to go from well to tank to tank down is long. The use of concrete into the conveyor belt conveyor belt to the concrete tank can be effectively avoided the above unsafe factors, save manpower and reduce labor intensity, and the simple operation, small amount of maintenance, it is worth promoting the application.
