MINE VENTILATION SYSTEMS

Depending on the size of mining entries, stopping sizes range from as small as 4-ft by 20-ft in low coal to as large as 30-ft by 40-ft in limestone mines. 2. Overcast/undercast Overcasts are air bridges where intake and return airways are required to cross each other. They could be constructed of masonry, concrete blocks, or pre-fabricated steel. 3. Regulator Regulators commonly are used to

Effect of Condenser Air Flow on the Performance of Split

The maximum rated air flow of the fan is 0.43 m3/s at 42ºC outdoor air temperature and the minimum is 0.28m3/s. To facilitate variation of refrigerant flow rate according to the evaporator load, the traditional capillary tube was replaced with a suitable thermostatic expansion valve and liquid refrigerant reserve. The influence of condenser airflow and its temperature on the A/C unit

Ventilation - Basic Mining Process/Terminology

A small quantity of air may flow through mine workings naturally but this would be insufficient and uncontrolled and therefore it is necessary to provide a mechanical means of ventilating the mine. To do this at least two connections between seam and surface are required and large fans are connected to one of these. These are primarily exhaust fans which suck air into the mine from the surface

A simple air conditioning circuit and cycle

This transfer of heat from the vapor to the flowing air is what makes hot air blow out of your air conditioner's condensing unit. At this stage in the air conditioning circuit and cycle diagram, high pressure liquid refrigerant will flow down the liquid line, through a filter drier that is designed to prevent contaminants from flowing through the system, and on to the metering device.

Reciprocating Compressor - Diagram, Parts,

Schematic diagram of the single-cylinder compressor is shown in Figure. Inlet stroke: – Suction or inlet stroke begins with the piston at the top dead center (a position providing a minimum or clearance volume). During the downward stroke, piston motion reduces the pressure inside the cylinder below the atmospheric pressure. The inlet valve then opens against the pressures of its spring and

Measuring Air Flow - ElectroSchematics

The mass air flow (MAF) sensor in an automobile converts the amount of air drawn into the engine into a voltage signal to calculate engine load. This is necessary to determine how much fuel to inject, when to ignite the cylinder, and when to shift the transmission. The air flow sensor is located directly in the intake air stream, between the air cleaner and throttle body where it can measure

About Drawing Schematic Diagrams | AutoCAD

A schematic drawing is a two-dimensional (2D), not-to-scale flow diagram that shows the logic and operation of a building system. You draft a schematic or single-line diagram of your system to use as a basis for your complete design layout, or to create plumbing riser diagrams or details associated with your design. Generally, drafting a schematic diagram is one of the first steps in the

Underground mine ventilation - Wikipedia

Underground mine ventilation provides a flow of air to the underground workings of a mine of sufficient volume to dilute and remove dust and noxious gases (typically NO x, SO 2, methane, CO 2 and CO) and to regulate temperature.The source of these gases are equipment that runs on diesel engines, blasting with explosives, and the orebody itself.
