The practice of ventilation is continually evolving with new technological advances developed in the mining industry. In recent years the advances in diesel engine technologies, ventilation modeling software, and ventilation management capacities have redefined the historical methods used to evaluate systems.
The mine ventilation system is connected with each working place underground, which has the overall influence on the mine ventilation and safety condition. The ventilation system should be established and improved in both newly designed mines and producing mines. A ventilation system should have at least one intake air shaft …
coal mine ventilation plans that are designed to control methane and respirable dust. 30 CFR. 75.371 specifies the minimum information that must be included in an underground coal mine ventilation plan. Additional information may be required to suit the particular conditions and mining system at the mine. 30 CFR. 75.372

In recent years the advances in diesel engine technologies, ventilation modeling software, and ventilation management capacities have redefined the historical methods used to evaluate systems. The advances re-evaluate …
The mine ventilation system consists of ventilation networks, ventilation power, and ventilation risk control facilities. The ventilation network is composed of all the …
A mine ventilation system consists of interconnected airways, work places and ventilation control devices. It can be represented as a network, in which the airways and work places are depicted as lines and the connection points of these lines as nodes. This representation permits application of Operations Research methods in analysis and …
Achievements in research on ventilation system stability have gradually been applied in mine ventilation practice [5, 20], but the following problems have also emerged: (1) emphasis is placed on quantitative analysis methods to evaluate ventilation system stability, and there have been few studies on airflow direction discrimination for …
A Ventilation Air Methane Thermal Oxidizer or VAMTOX is a specialized type of the thermal oxidizer, designed to handle methane produced by mining. Conifer Systems' VAMTOX solutions consists of multiple RTOs based on the scale of the mine and its activities. The RTOs are highly efficient with a DRE between 95%-98% and typically …

The constant air quantity β is mainly dependent on the ore handling system and, to a certain extent, on the overall mine production rate. For mines where rock is transported through a decline using diesel powered truck haulage or there is no crushing of the mined rock, a suitable value of β is 50 m 3 /s. This typically increases to 100 m 3 /s …

Large room-and-pillar stone mining fundamentals. The value per ton of ore for large room-and-pillar stone mines is typically low, therefore productivity must be high. Typical face areas are 12.2 m wide x 7.6 m high (40 ft wide by 25 ft high) with 4.3 m (14 ft) pulled with each blast (Figure 1). This equates to over 1,000 tons of stone per ...
