[vc_row css=”.vc_custom_1455449288036{margin-top: 30px !important;}”][vc_column][vc_column_text]This machine is used for drilling blast holes with a diameter of 51mm and a depth of 20 m according to a defined pattern.
The blasting holes can optionally be drilled vertically or inclined. To work with a circular drilling rig СКП-70 in a gallery, a cross section of at least 6.5 m2 is required.
The hardness of the drilled rock (as per Prof. Protodyakov) must be in the range of f=8÷30.
The circular drilling rigs СКП-70 are equipped with heavy drilling hammers, such as ВВС 120-F [/vc_column_text][/vc_column][/vc_row][vc_row css=”.vc_custom_1455449288036{margin-top: 30px !important;}”][vc_column][vc_column_text]
