Wirtgen surface miners allow limestone to be mined in Ube Isa quarry in an environmentally friendly way that doesn’t affect the surrounding area.
Surface miners can be used to cut significantly steeper mining walls (top of picture) than with the conventional blasting method (bottom of picture). This maximizes the use of the deposits.
Mr. Tomoyuki Shodai, General Manager of Mining Department at Ube Industries, about the benefits of Wirtgen surface miners in the Ube Isa for his company.
The 2500 SM Vario surface miner guarantees stable and high-precision mining operations – and can create quarry faces at up to a 70° angle with extremely narrow benches
Okumura Engineering Corporation has been using surface miners from Wirtgen GmbH in the mining of rock for many years. The company has been active in Ube since 2012.
Using the remote control, the operator can easily operate the 2500 SM Vario from outside the machine, making the mining process much safer on steep slopes.
In combination with the HT15 quick-change toolholder system, the cutting tools with a shank diameter of 42 mm are ideal for cutting hard rock types.
