Cutting scale safely in the coal mine shaft

Against excessive shaft crevice water and large scale in the shaft wall that lead to lock the cage and threaten coal mine's safely lifting all the time in the Tongye Coal Mine shaft, a new type cutting scale equipment, cutting scale machine type SGQ-1, was developed. Cutting experiment and practical application show that it can adapt to abominable condition in well, such as narrow space, wet and excessive shaft crevice water etc, and can run safely and reliably, and has high cutting scale efficiency.
