What Are the Different Underground Mining Jobs?

The underground mining method refers to the process of extracting ore from the ore block of the underground ore deposit. It is realized through four steps: ore development, ore extraction, cutting and mining. There are many types of underground mining methods, and the commonly used ground pressure management methods are divided into three categories: natural support mining methods, artificial support mining methods, and caving mining methods. The underground mining system mainly includes production management, rock drilling, blasting, mining, skating system, underground crushing, bucket hoisting, and hoisting system. The main steps of underground mining, common methods, and the safety rules corresponding to different methods are introduced in detail.

Underground mining is a general term for using underground operations to open mining beds. Mainly refers to production

Mining work excavates a series of roadways to create conditions for cutting and mining work; cutting work forms free surface and falling space for mining work; mining work extracts ore from the mining face, including mining, mining and ground pressure management. Kind of homework. There are many types of mining methods.

The selection of mining methods should consider the geological conditions of the deposit, technical conditions of the mine, and economic factors to meet the requirements of safety, economy, efficiency and quality. The geological conditions of the deposit include the shape, inclination, thickness, distribution of useful components, physical, mechanical, and chemical properties of surrounding rocks and ores; the technical conditions of the mine include the supply of materials, equipment and labor, the requirements of the processing department for the ore, and the surface Environmental requirements and technical management level; economic factors include ore value, cost, profitability, comprehensive utilization of resources, and national economic requirements. According to the above conditions, several schemes are selected, and the optimal scheme is determined after comprehensive technical and economic comparisons, which are officially used after passing industrial tests.

Underground mining methods

Exploitation of ore deposits. Different ore deposit development methods are selected according to the occurrence conditions of the ore deposit and the occurrence of the ore body to facilitate transportation, pedestrians, ventilation and drainage.

Underground mining methods

The mining standard of ore blocks refers to the excavation of a series of roadways according to predetermined plans and drawings, thereby creating the necessary conditions for the cutting and mining of ore blocks.

Underground mining method cutting

On the basis of mining standard work, the nugget cutters open up free surfaces and ore falling space for the mined stone, thereby creating the necessary working conditions for the nugget mining.

Underground mining method

Mining is the process of mining ore from ore blocks and is the core of mining. Stopping usually includes 3 types of operations:

Falling ore: the operation of mining the ore from the ore body with a suitable block size;

Mining: the operation of transporting the mined ore from the mining face to the stage transportation level;

Ground pressure management: Including the use of pillars, backfills and various supports to maintain the goaf. ^[1]
