Description
Technical field
The present invention relates to a kind of slot raise blasthole laying out apparatus, more particularly to a kind of slot raise snubber is accurately put
Sampling device.The invention further relates to the using method of the accurate laying out apparatus of slot raise snubber.
Background technology
In the exploitation of metallic ore underground mine stope, slot raise creates the scope of freedom and compensation space for follow-up back production,
The drilling quality of snubber is extremely important factor in slot raise construction.Especially for underground mine stope middle-deep well chisel
Rock bench wagon drill hole simultaneous shaft sin king blasting technique is (such as Fig. 1, in figure：14- ore bodies, 15- slot raises region, 16- slottings region, 15-
Tunnel), generally using parallel burn- cut method (such as Fig. 2, in figure：18- burst regions, circles blasthole of 19- second (reliever), 20-
Slotting region), because borehole spacing is less, (such as Fig. 3, K represents the blasthole i.e. emptying aperture of not blasting charge in figure, and remaining blasthole loads fried
Medicine), usually occur the undesirable elements such as perforation and perforations adding in construction, therefore have very high requirement to the drilling oxygen evolution rate of snubber.
And without general snubber setting-out mode in prior art, be only through field worker and combine the skilled of itself according to design drawing
Degree is estimated and setting-out goes out, and oxygen evolution rate has larger difference according to operator's skills involved in the labour, thus, often setting-out goes out
Cut shot is larger with drawing trueness error, and in creeping into especially for blasthole closer to the distance, drilling perforation usually occurs, big gun
Distance between borehole deviation is larger, perforations adding, the low blasthole of rock drilling equipment efficiency are retouched hole difficulty increase, initiation net design and powder charge difficulty and increased
