Shaft development refers to the overall design of the shaft layout, engineering implementation and mining deployment for the entire mine and each level of mining. A successful exploration method should be both technically feasible and economically reasonable while ensuring safe and efficient production. The main elements of well field development include determining the form, number and location of wellbores, as well as dividing the mining level, arranging equipment, and preparing methods.
The success of a well field’s development is not only related to long-term production interests but also to infrastructure works, initial investment, and construction speed, which ultimately impact the economic benefits of the mine. Therefore, determining the development method should follow these principles:
Implement national technical policies for coal industry development to reduce unnecessary work while ensuring reliable and safe production. This includes reducing initial construction work, saving infrastructure investment costs, and speeding up mine construction.
Reasonably centralize exploration deployment to simplify production systems and avoid dispersion in production operations while achieving centralized production.
Develop national resources reasonably to minimize coal losses.
Implement relevant regulations on coal mine safety by establishing a complete production system that frequently maintains primary roadways for optimal use.
Adapt to current national technical levels and equipment supply while creating conditions for adopting new technologies, techniques, mechanization methods such as comprehensive mechanization or direct motion technology in coal mining operations.
