Embodiment 1

[0018] An open-pit residual ore recovery and collection process, the process comprises the following steps:

[0019] (1) Geological survey: randomly select a survey site in the residual mining area as the survey origin, take the survey origin as the center of the circle, and select three survey floating points at equal intervals on a circle with a radius of 50 meters, and then use the three survey floating points as Center of the circle, take the distance between any two survey floating points as the radius, take the intersection of the three circles as the survey base point, and again take the survey base point as the center, repeat the above method to determine the rest of the survey base points, in the survey origin, survey Geological detectors are installed at the floating point and the survey base point, and the real-time geological information of the residual mining area is obtained and recorded;

[0020] (2) Division of residual mining areas: According to the results of...

Abstract

The invention discloses a process for recycling and collecting open residual ore, comprising the following steps: geological exploration, residual core classifying, flat zone recycling, trimmed zone recycling, corner zone recycling, and residual ore recycling. The process enables scientific and reasonable mine collection and provides efficient recycling and collection for open residual ores, recycling utilization of open residual ores is greatly increased, geological exploitation and different collection modes for various areas ensure both collecting speed and efficiency of residual ores, great economic benefit and survival space are provided for enterprises, and important practical significance is brought for mine resource crisis.

Description

technical field [0001] The invention belongs to the field of residual ore recovery, in particular to an open-pit residual ore recovery and collection process. Background technique [0002] According to statistics at home and abroad, after open-pit mining, the amount of ore remaining around the open-pit accounts for 5% to 16% of the total reserves. Because these residual ore bodies do not meet the requirements of the economic stripping ratio or do not meet the conventional mining conditions, they cannot be recycled during mining production. Most of the large and medium-sized mines in my country were first built in the 1950s. After decades of mining, at present, more than half of the mines have entered the middle and late mining stages, and are facing the pressure of closing pits and stopping production. [0003] Therefore, according to the specific conditions of each residual ore body, relying on the current production technical conditions of the mine, and on the premise of ...
