Deeply-buried steeply-inclined ore body exploration method

Abstract

The invention discloses a deeply-buried steeply-inclined ore body exploration method, which mainly comprises the following steps of: determining a regional structure background of a large deeply-buried steeply-inclined ore body deposit and structure evolution of a region where the large deeply-buried steeply-inclined ore body deposit is located, and re-determining a magmatic rock type and an invasion sequence of the deposit of the type, the method comprises the following steps: determining ore-bearing rock masses and formation times of a large-scale deeply-buried steeply-inclined ore deposit, clarifying the properties of metallogenic magmatic rocks, magmatic origin and evolution and a restrictive relationship to formation of the deposit, performing staging exploration according to mining elevations, determining mine stoping sequence elevations according to a mine stoping sequence, performing exploration in each stoping elevation, and performing exploration net degree research, so as to achieve the purpose of exploring the ore-bearing rock masses of the large-scale deeply-buried steeply-inclined ore deposit and the formation time of the ore-bearing rock masses of the large-scale deeply-buried steeply-inclined ore deposit. And determining the exploration type of the engineering interval of new mining area exploration according to the result of the previous steps. According to the design and construction of the exploration and mining combined project, the mine construction process is accelerated.

Description

Technical field: [0001] The invention relates to a deep-buried and steeply inclined ore body exploration method, which belongs to the technical field of solid mineral exploration. Background technique: [0002] During the exploration of similar deep (>500m) solid minerals at home and abroad, after detailed investigation of mining areas with industrial value (controlling resources account for 20-30%), surface drilling construction is carried out in the exploration range, and the exploration report is used as mine construction. Basis for design. The traditional construction of exploration drilling on the surface makes exploration of all the middle sections of the ore body within the first mining plane range lead to a large amount of drilling work in the early stage, especially for ore bodies with deep burial and steep dip angles, which require high directional construction accuracy and long exploration periods. Difficulty (directive drilling is required to control the incl...

Problems solved by technology

The traditional construction of exploration drilling on the surface makes exploration of all the middle sections of the ore body within the first mining plane range lead to a large amount of drilling work in the early stage, especially for ore bodies with deep burial and steep dip angles, which require high directional construction accuracy and long exploration periods. Difficulty (directive drilling is required to control the inclination of steeply inclined ore bodies, and the current wireline core drilling technology is difficult to achieve, and the drilling deflection control accuracy of deep hole general drilling construction technology is difficult to meet the requirements of the exploration stage), long construction period (large drilling volume , low efficiency), high cost, complex construction site conditions (topography, road occupation, land acquisition difficulties), etc.
