Kanahira mining reserves 8 to 10 billions limestone which was metamorphosed from normal limestone to crystallized limestone(i.e. marble) by heat of magma. This crystallized limestone(marble) is superior than others in whiteness and purity. So fine chemical market need our crystallized limestone(marble) year after year.

What is safety and practical mining system?

Our mining system is called “Room and Pillar Mining”. Handling jumbo drill, large shovel and big dump truck, we proceed mining deliberately. “Room and Pillar Mining” is superior than “Open pit Mining” in avoiding contamination of topsoil and able to operate safely and deliberately. In addition limestone deposit is very tough and strong so that even hit by a strong earthquake the deposit is never destroyed. We have no risk of poison gas. So we never experienced mining accident since we had started this mining.
