A method of delineating ore bodies

Abstract

The invention discloses a method for delineating an ore body, comprising the following steps: step 1: arranging exploration lines perpendicular to the trend of the ore body, and arranging fan-shaped drilling holes on each exploration line; Hole histogram, step 3: According to the actual measurement results of the borehole, reflect the drill hole on the profile and plan view, step 4: Then reflect the ore-seeing situation of the drill hole histogram to the profile and plan view, step 5: According to The ore body is delineated by the entry and exit points of each borehole on the profile diagram. Step 6: Collect the secondary delineation geological data of the stope in the middle section of the mining, especially the secondary delineation geological data of the stope located on the exploration line. The method of delineating the ore body adopts the comparison method of exploration and mining data to verify the correctness of the original data and the rationality of the exploration work, which is conducive to the layout of the mining and cutting works, making the layout more reasonable, and helps to reduce blasting ores and mining costs. , improve profitability.

Description

technical field [0001] The invention relates to the related technical field of delineating an ore body, in particular to a method for delineating an ore body. Background technique [0002] Ore body delineation mainly refers to the work carried out through geological research and engineering disclosure to trace and find out the shape, occurrence, spatial distribution and scale of the ore body. In the calculation of mineral reserves, according to the data of prospecting engineering and sampling analysis, and according to the index requirements of the industrial sector for mineral utilization, the work carried out to determine the distribution range of mineral reserves of different qualities, uses and mining technical conditions is also called ore body delineation. [0003] The method of using in-pit drilling to delineate the ore body for infrastructure exploration in the mine is basically the following seven steps: 1. Layout exploration lines perpendicular to the direction of ...

Problems solved by technology

[0005] The object of the present invention is to provide a kind of method of delineating ore body, to solve the ore body delineation step of the prior art proposed in the above-mentioned background technology, when drilling is deep or when carrying out prospecting from ore body floor construction, due to the bottom plate enclosing The rock is hard and broken, and the drill hole is deep and the inclination angle is less than ∠-45°. When the inclination measurement of the drill hole cannot be carried out, the ore-exit point and the actual position of the drill hole are quite different from the actual position. The delineated ore body also has a large displacement from the actual position of the ore body, which brings relatively great difficulties to mining technicians in arranging mining and cutting projects, which is not conducive to the economical and reasonable recovery of the ore body.
