マイン・オンライン・システムの採用による深沢鉱山の近代化

抄録

Fukasawa Mine is a kuroko mine, developed and operated with a fully trackless sytem. The cut and fill method with artificial roofing is applied; about 20 drift headings spread throughout an area of 2.0km by 1.0km and are generally being worked on to produce 26, 500t of crude are per month. These drift driving works progress in cycles of drilling and blasting, mucking, and timber supporting.
The development of Mine On-Line System (MOS) is composed of innovations on mining machines and underground communication; it aims to establish the optimum combination of workers, machines, and drift headings. Innovations in mining machines include the development of cross-cut jumbos, timbering machines, and scale-up of loaders. An innovation in underground communication is the adoption of the integrated underground communication system combined with a personal computer.
A drastic improvement of worker's performance has already been observed and further improvement is expected.
The mine production is scheduled to increase to 30, 000t per month in the near future, due essentially to the improvement of productivity as a result of the MOS project.
