Heat Treatment and Ventilation Optimization in a Deep Mine

In order to address the issue of high temperatures and thermal damages in deep mines the factors causing downhole heat damage at high temperatures were analyzed the mine ventilation system was optimized and rebuilt and a cooling system was established. The proposed cooling system uses mine water as the cooling source and its features are based on the analysis of traditional cooling systems

Field Study of Longwall Coal Mine Ventilation and Bleeder

wall mines use bleeder fans to remove methane-laden air from these areas inby the active longwall face. The use of bleeder ventilation networks in U.S. mines was documented by Kingery and Dornenburg (1957) as applied to room-and-pillar mines. Since that time large-dimension longwall panels have evolved in the U.S. coal mining industry.

A study of leakage rates through mine seals in underground

Seals are widely used in underground US coal mines to isolate mined-out workings thereby reducing the ventilation load for the mine. With increased longwall panel sizes being realised by current mining equipment large mined-out areas of coal mines must be either ventilated or isolated from active workings by mine seals.
