11 This code is for geological exploration work

The basic guidelines stipulate the type of exploration, the degree of exploration, the amount of engineering, the technical requirements for exploration, and the geological assessment and evaluation of hydrological and geological engineering geological environment in the mining area.

Basic requirements for report writing.

1.2 This code is applicable to hydrogeological engineering geological exploration in solid mineral mining areas.

Basis for preparation and review.

3 General

3.1 Basic tasks of exploration work

3.1.1 Find out the hydrogeological conditions of the mining area and the water-filling factors of the deposit, and predict the amount of water in the pit. To evaluate the comprehensive utilization of mineral water resources,

Out of the water supply direction.

3.1.2 Find out the engineering geological conditions of the mining area, evaluate the rock mass quality and slope stability of the open-pit mining site, or the rock mass quality of the surrounding rock

And robustness, predicting major engineering geological issues that may occur.

3.1.3 Comment on the quality of the geological environment of the mining area, predict the main environmental geological problems that may occur due to the development of the deposit, and put forward suggestions for prevention and control.

3.2 Stages of exploration work and requirements

The hydrogeological engineering geological survey and environmental geological survey and evaluation of the mining area shall be compatible with the mineral geological exploration work stage, and are divided into general surveys and detailed surveys.

Three stages of investigation and exploration. In mining areas with simple hydrogeological and engineering geological conditions, the exploration phase can be simplified or merged. But provide mine construction equipment

The geological survey report used as the basis shall meet the requirements of the exploration stage.

General survey stage: Combined with mineral census, the data of areas where regional hydrogeological engineering geological survey has been conducted can be directly used.

Use or only conduct targeted supplementary surveys to roughly identify hydrogeological, engineering, and environmental geological conditions in the work area.

Detailed investigation stage: Basically find out the hydrogeological engineering geology and environmental geological conditions of the mining area.

Provide the basis for the construction planning of the mine and the exploration design of the mining area.
