目前由山东省莱州市柞村镇消水庄村农民王振周研制的花岗岩切割专用机械———矿山火焰切石机获得中国专利。我国目前各地矿山花岗岩矿体的分割剥离大多采用人工炮轰方式,由于花岗岩石质坚硬,因此开采加工难度相当大,除开采生产效率较低外,更存在严重的安全隐患和石材资源破坏
At present, the granite cutting special machinery --- mine flame stone cutting machine developed by Wang Zhenzhou, a consumer of Zhuozhe village of Qiao village in Laizhou city of Shandong province, obtained Chinese patent. At present, most of the granite ore bodies in our country are mostly divided and separated by artificial bombardment methods. Due to the hard rock granite, the mining and processing is quite difficult. In addition to the low production efficiency, there are serious potential safety hazards and stone resource destruction
