The specific embodiment
Following term in the utility model does not need to carry out specific description again in manual:
" first selecting arrangement " is used for determining next overburden operation face at distance mining face 28-32 rice;
" second selecting arrangement " is used for determining next mining face at distance overburden operation face 28-32 rice;
" bearing unit " is the drilling tool of described drilling equipment, is used for making the axis of shot hole be parallel to the ore body inclined plane.
" first selecting arrangement ", " second selecting arrangement " they itself all are well-known to those having ordinary skill in the art, have multiple choices, for example, and position indicator, non-contact distance-measurement instrument etc." bearing unit " itself is well-known to those having ordinary skill in the art, and those skilled in the art can select fully as required.
" communication connection " in " first selecting arrangement is connected with at least one drilling equipment communication ", " second selecting arrangement is connected with at least one drilling equipment communication " itself is well-known to those having ordinary skill in the art, have multiple choices, can wire communication, also infinitely communication.
The transfer of data of " selecting arrangement " belongs to common practise for " drilling equipment ", does not also need to carry out in manual specific description again.
Shown in Fig. 1-2, the excavating plant 50 that side slope line 1 and form line 3 center on has A side and B side.Excavating plant 50 has a series of inclined orebodies 2.The utility model adopts the mode of ore deposit useless dislocation explosion 90 alternately to handle overburden operation face 20 and mining face 10.The country rock (overburden operation face 20) that Fig. 1 represents to peel off the left side formerly, and then at mining face 10 production ores, the dislocation distance L of back production and overburden operation face is not less than 28 meters.Fig. 2 represents that vertical hole can increase the position of ore dilution rate and loss late; Simultaneously, reflect intuitively that also inclined drill can not hold the reason of operation from A.Because are inwardly " drawing " less than 90 ° operations, also can directly increase ore dilution rate and loss late.
Be to hole along ore body tendency (shown in arrow D among Fig. 2) according to rock drilling big gun of the present utility model hole implementer's case; The sequence of operation is changed into the outside (shown among Fig. 2 30) beginning of ore body tendency by two ends operation simultaneously; It is not far that the quarrel distance is thrown in loosening blasting, peels off with the dislocation of digging up mine and carry out explosion (shown among Fig. 1 10,20), and the distance L that staggers approximately is about 30 meters of the distance of secondary blasting operation, like this, can avoid the useless heap that mixes in ore deposit well.
Fig. 1 and Fig. 2 have shown main, the main part of system architecture, those skilled in the art such as remaining " communication connection ", " selecting arrangement ", " drilling equipment " understand easily, do not need to be labeled in again on Fig. 1 and Fig. 2 requirement succinct to satisfy, that understand.
The utility model provides a kind of implementation system of improving one's methods of adopting stripping rock drilling operation technique, and it can be advantageously applied in the stoping operation of surface mine inclined orebody.Peel off bursting work face 20 earlier, the production ore scope of operation 10 again, horsestone in the middle of the stripping, and then production ore again.Comprise forward Drilling country rock (shown in arrow D among Fig. 2), explosion shovel loads and transports out, Drilling ore body (shown in arrow D among Fig. 2) forward, and the explosion shovel takes on the ore deposit, also can carry out the 3rd or the 4th time driling explosion according to this, makes that adopting the stripping operation carries out continuously.The utlity model has conveniently, do not need to do other investment, just inclined drill is a bit dark relatively.
According to the utility model, the mining technology of the explosion of implementing forward to hole, to misplace can reduce the rate of dilution and loss late effectively.Forward the drilling and blasting country rock treats that leading about 30 meters of country rock overburden operation face enter forward drilling and blasting of the first lump ore body; Treat that the ore body scope of operation enters country rock overburden operation for the second time for leading about 30 meters, also can carry out according to this adopting the stripping operation the 3rd or the 4th time, adopt the stripping operation at this platform and finish a half that can adopt the stripping operation again simultaneously at next platform, technology is the same.
According to the utility model, by the mode of angling hole explosion, avoided a side to adopt into a leg-of-mutton barren rock, the situation that opposite side has lost a leg-of-mutton ore takes place.According to the utility model, by the dislocation explosion, make that again the rock burst broken heap that divides in ore deposit is better, made things convenient for and adopted the stripping operation, reduced impoverishment rate in mining and loss late effectively, avoided the cross influence in the operation process.
