Method for delineating ore body

Abstract

The invention discloses a method for delineating an ore body. The method comprises the following steps that 1, exploration lines are arranged vertical to the trend of the ore body and fan-shaped drill holes are formed on each exploration line; 2, after drill hole construction, recording is carried out to form a drill hole histogram; 3, the drill holes are reflected on a profile map and a plane map according to the actual measurement result of the drill holes; 4, the ore finding condition of the drill hole histogram is reflected to the profile map and the plane map; 5, the ore body is delineated according to an ore entering point and an ore exiting point of each drill hole on the profile map; and 6, secondary delineating geological data of a mined middle-section stope, especially the secondary delineating geological data of the stope located on an exploration line are collected. According to the method for delineating the ore body, an exploration and mining data comparison method is adopted, the correctness degree of original data and the rationality of exploration work are verified, arrangement of mining and cutting engineering is facilitated, arrangement tends to be more reasonable, ore blasting reduction and mining cost reduction are facilitated, and the profit level is improved.

Description

technical field [0001] The invention relates to the related technical field of delineating ore bodies, in particular to a method for delineating ore bodies. Background technique [0002] Ore body delineation mainly refers to the work carried out by tracing and finding out the shape, occurrence, spatial distribution and scale of ore bodies through geological research and engineering disclosure. In the calculation of mineral reserves, according to the data of prospecting engineering and sampling analysis, and in accordance with the requirements of industrial departments for mineral utilization indicators, the work carried out to determine the distribution range of mineral reserves with different qualities, uses and mining technical conditions is also called orebody delineation. [0003] For infrastructure prospecting in mines, the method of using in-pit drilling to delineate the ore body will basically follow seven steps: 1. Arrange exploration lines perpendicular to the direc...

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.
