Description
Technical field
The present invention relates to geological exploration technical fields, particularly, are related to a kind of rock stratum identified based on rock drilling impulsive sound point
Interface technique for delineating.
Background technology
It is influenced by geological structure, the scale of ore body, form, occurrence are more complex, although early period, mine locating was met
Adopt the needs of quasi- design, but in recovery phase due to being limited by mine locating net degree, to prolonging on ore body, sagging, branch, turnover
Mineralising continuity degree, complex shape degree, upper lower burrs boundary and horsestone between position and rock drilling segmentation is between rock drilling segmentation
Variation can not accurately control.Therefore in back production, ore losses, Rock dilution will be caused in a certain range, causes mine
Stone loss and dilution, and the blindness of ore limits is an important factor for leading to poor damage index superelevation.Therefore, we must be by complete
Kind mine locating work, preferably grasps the actual form of ore body, just can preferably solve the problems, such as this.
Mining production mine locating carries out in mineral deposit after detailed exploration, and Main is the special mine locating work of arrangement
Journey is prospected using opening up, adopting accurate, each stage arrangement of cutting engineering, since the spacing between engineering is larger, between engineering
Ore body situation by infer determine, such as high-dipping middle thickness orebody, using sublevel open stope method back production, height of lift is generally 10
~15m or so, sublevel drilling tunnel along stope trend be arranged in arteries and veins, in order to visit clear ore body thickness direction ore limits,
Generally in sublevel drilling tunnel side, driving wears arteries and veins and discloses ore limits, remaining position is inferred according to arteries and veins exposure situation is worn, and is shown
Its right net degree is still larger, and accuracy is not still high.
By taking the mine using medium-length hole or borehole drilling as an example, blasthole array pitch is in 1.5~4m in 1.5~4m, bottom hole pitch
Uniform lumpiness is obtained after explosion, it is desirable that blasthole is waiting for that it is best that mining is uniformly distributed in vivo, therefore can utilize back production rock drilling big gun
Hole can solve the problems, such as that mine locating net degree is low as prospecting means.For this purpose, a large amount of mines are explored, have studied：
1, the method for taking medium-length hole return slag rock powder to chemically examine.Part concentrate, product will be taken away due to returning to slurries out of hole
Position error is larger；Second is that chemical examination heavy workload, promptness is poor, and live rock drilling cannot be instructed to work in time.
2, medium-length hole magnetic spy method.With limitation, it is not suitable for non-magnetic ore body mine locating.
3, different according to ore-rock color, observation long and medium hole drilling returns the boundary that pulp color judges ore-rock.According to ore-rock color
Judgment method cannot judge on the one hand when ore-rock color is close；On the other hand since blasthole has certain stroke, rock drilling to return
Slurry needs the regular hour, the narrow space between drilling-rod external wall and blasthole wall, and rock slag is unable to horse sometimes during blasthole drilling
Upper exclusion, color is difficult to differentiate between after the mixing of different lithology return slag, and the reasons such as underground work visuality difference are but also boundary is difficult to sentence
It is disconnected.
The above-mentioned method prospected using back production rock drilling improves the accuracy of the termination of ore body, but can by its process
Know, is required to geomatics engineer whole process and carries out sampling operation of joining a regular shift or class, labor intensity is big, artificial to expend greatly.
Invention content
The present invention provides a kind of rock stratum interface technique for delineating based on the identification of rock drilling impulsive sound, to solve existing production
Mine locating technology promptness is poor, and geomatics engineer labor intensity is big；Deep hole mine locating proposes brill or coring repeatedly, and mine locating is of high cost,
