Description
Technical field
The utility model relates to blasting technique fields, and in particular to a kind of ammonium nitrate-fuel oil mixture dress of Novel underground mine blasting
Medicine device.
Background technique
With background technique: at present in mine, build the road, often use explosive in bridge tunnel, hydroelectric project, especially mine underground is opened
It adopts and has entered the mechanical automation epoch, mine underground exploitation is all to use special explosive loader under normal circumstances, is set on explosive loader
Have drain hole, explosive is contained in explosive loader, explosive is sent by blasthole by control drain hole, mining area be often drilled with compared with
More blastholes, and the position of blasthole is again intricate, the distance between different blastholes are also difficult to control, for the blasthole of different location
Explosive is installed, the way of the prior art and is sent explosive to blasthole by the way that explosive loader to be transferred at different blastholes.
There are biggish defects for this way of the prior art: firstly, explosive loader volume and weight itself is all relatively large,
Transfer explosive loader will pay biggish human and material resources every time, greatly reduce the working efficiency of blasting excavation, and turn every time
The process for moving explosive loader can all generate some potential safety problems, cause centainly to threaten to the safety of operator；Secondly, mine is made
Industry face is often with a varied topography, since explosive loader own vol is larger, places explosive loader and needs to find suitable specific location, and makees
Industry face landform is often uneven, therefore when can not find suitable placement location, needs in the position close to blasthole to ground
It carries out levelling and tamps, this way more affects the job schedule of explosion, therefore explosive loader in the prior art is remote
Far from meeting blast working.
Utility model content
