Computer Aided Design Of Mine Compressed Air Networks - Introduction

Compressed air distribution networks are essential for powering equipment in many mines even though some mines are replacing them with electrical power for hydraulic drills. Compressed air can be costly especially if the system is poorly designed and maintained. This paper outlines a technique for proper compressed air system design that will help mine managers reduce compressed air power costs; an important topic in today's highly competitive international minerals market. Compressed air system design is complex. It requires specifying: 1) air quantity and pressure in all branches of a large network, 2) proper location and types of valves and fittings, 3) the network solution that determines compressor requirements, 4) optimal hose and pipe, diameters, 5) receiver and compressor accessories, and 6) required capital and operating costs.
