The need for underground industrial space is discussed, the characteristics which make a mine suitable for secondary industrial development and use are described, the various methods of development are reviewed, and comments are made on the comparative economics of development alternatives. The advantages of underground storage and manufacturing sites are listed. To be suitable for underground industrial usage after mining, the rooms must be of adequate size, it must have a competent roof, the pillars must be of sufficient size and strength to support all loads, the floor rock must be strong enough to prevent heaving or pillar settling, surface drainage and groundwater conditions must prevent water influx into the mine openings, and the openings must be easily accessible. The general design of the developed area may include round or square pillar support, rib pillars, or the modular concept which consists of large modules with rib pillars more widely separated and intermediate support provided by round or square pillars. The type of access provided for rail or truck haulage is dependent upon the volume of material to be moved per day in the secondary phase. Some cost advantages and income tax savings may be achieved in planning the mining system and the conversion of the space for industrial usage. An example is presented to describe the conversion into secondary use of a limestone mine producing 600,000 tones of stone per year.
