Abstract
The invention discloses an exploration and mining combination method of an ore body exploration entry. The method includes the steps that firstly, a developing entry is pre-distributed according to known ore body data; secondly, the exploration entry is designed on the inevitable way of the developing entry; thirdly, an exploration access is distributed perpendicular to an ore body and penetrates through the ore body, and the boundary of the ore body inclining to ore rock and the thickness of the ore body are determined; fourthly, the exploration entry is distributed in the middle of the ore body along the ore body, and the boundary of the ore rock is found in the direction; fifthly, a short exploration entry perpendicular to the direction of the ore body is distributed along the tunneling of the exploration entry in the direction of the ore body, and accordingly ore control precision of the entry in the direction is guaranteed. The method has the beneficial effects that a traditional exploration method achieved by finding the ore rock boundary is replaced, and the exploration and mining combination method is closely combined with the mining method, so that entry engineering amount is reduced, exploration and mining are combined, and the aim of reducing mining cost, the dilution rate and the loss rate is achieved.
Description
Technical field
The invention belongs to mining technique field, relate to the prospecting in mining method in mine locating lane.
Background technology
Sublevel caving method without sill pillar is applicable to inclined thick gulf, and domestic iron ore mine of adopting substantially all adopts the method to dig up mine.But for some number mines, the occurrence patterns of ore body and irregularity, exploitation form undesirable be long and narrow narrow ore body.Also having some mines also to there is ore body major part is thick large high-dipping, but remainder, particularly ore limits part is irregular, still has certain the blind area of control, needs to carry out production mine locating in real time, increases control accuracy.For the long and narrow narrow ore body in down-hole and thick large high-dipping ore block irregularity boundary part with traditional capwise gallery (as shown in Figure 1,4-prospect tunnel, 5-intend arranging tunnel, 6-boundary line of ore bed and rock, 7-lane along the pulse), Dai Yan then can be caused many, and rock mixing in rock intersection ore deposit, ore deposit causes unnecessary dilution, loss; Roadway engineering amount is bigger than normal, and cost is high, the problem that the rate of dilution of ore extraction is large, loss late is large, cost is high.
Summary of the invention
The present invention, for solving above technical problem, proposes a kind of prospecting in mining method of lane of prospecting.To reach the object reducing mining cost, the rate of dilution, loss late.
Technical scheme: the prospecting in mining method in ore body mine locating lane, step is as follows: a. is according to the development heading of known underground mining layer data pre-arranged; B. mine locating lane must be designed in development heading on path; C. vertical orebody trend arranges that a mine locating route penetrates ore body, determines rock border, orebody strike ore deposit and orebody thickness; D. in the mine locating lane of ore body intermediate arrangement one along orebody trend, push away and look for Kuang Yan border, across pitch ore deposit; E. along with the short lane of the mine locating of vertical orebody trend is arranged in the propelling in the mine locating lane of orebody trend, to guarantee the control ore deposit accuracy in tunnel, across pitch direction.
Beneficial effect: 1, traditional perpendicular to orebody trend, gallery mode is arranged to arrange that along orebody trend mode gallery substitutes for the long and narrow narrow ore body in down-hole and thick large high-dipping ore block irregularity boundary part;
2, prospect tunnel is arranged in the middle of ore body, in the middle of ore body, push away the rock border, ore deposit looked for along orebody trend direction.
3, according to engineering geological conditions and back production parameter, a mine locating route perpendicular to trend is arranged every 2 of development heading or multiple drift interval, to reach the object controlling rock border, orebody strike ore deposit;
4, instead of the survey methods on traditional rock border, searching ore deposit and combine closely with mining methods, roadway engineering amount being reduced, accomplishes prospecting in mining, to reach the object reducing mining cost, the rate of dilution, loss late.

Fig. 1 is traditional capwise gallery schematic diagram;
Fig. 2 is this method roadway layout schematic diagram;
Fig. 3 is this method embody rule example schematic.
Detailed description of the invention
As figure, according to the development heading of known underground mining layer data pre-arranged; Mine locating lane must be designed on path in development heading; Vertical orebody trend arranges that a mine locating route 1 penetrates ore body, determines rock border, orebody strike ore deposit and orebody thickness; In the mine locating lane 2 of ore body intermediate arrangement one along orebody trend, push away and look for Kuang Yan border, across pitch ore deposit; According to engineering geological conditions, arrange a short lane 3 of mine locating perpendicular to trend, to push away the rock border, ore deposit (see Fig. 2, arrow is explorating direction) looking for orebody strike direction every 2 of development heading or multiple drift interval.Guarantee the control ore deposit accuracy in tunnel, across pitch direction.The section of prospect tunnel is identical with the section of development heading, with the Mining entrance used as follow-up mining and ore removal loop.
Experiment embodiment, to the west of certain ore deposit ore body 3 exploration line, part ore body end is anxious receives pinching, is the long and narrow narrow Feature of The Orebody of big thick ore body irregularity boundary.Within the scope of the maximum haul distance of electric LHD, to arrange that along orebody trend mine locating direction, lane replaces vertical orebody trend arrangement, roadway engineering amount saves nearly half, and unnecessary country rock will be avoided in exploitation process to be mixed into will improve rate of extraction (see figure 3) further.
