本世纪六十年代开始,在国内外采矿工程中,井巷的支护已由一般支护型式演变为喷射混凝土及锚杆支护,这被认为是矿山工程的发展成果之一。当今,如何进一步高效率地发展喷射混凝土支护,这已成为刻不容缓待解决的问题。实践证明,合理的选用设备配套,尽快实现喷射混凝土机械化作业线,是提高喷射混凝土作业效率的有效途径之一。我司喷射混凝土机械化作业线由喷射 Beginning in the 1960s, in the mining engineering at home and abroad, the support of the shaft has evolved from the general support type to the shotcrete and bolt support, which is considered as one of the achievements of the mine engineering. Nowadays, how to further develop sprayed concrete support efficiently has become an urgent issue to be solved. Practice has proved that the reasonable selection of equipment, as soon as possible to achieve mechanized sprayed concrete line is to improve the efficiency of shotcrete one of the effective ways.
