Description
The BP-65M machine is designed for drilling blast wells with a diameter of 51-64 mm during underground mining of minerals in rocks with a strength coefficient f = 6 ... 20 on the scale of Prof. M.M. Protodiakonov with a pneumatic perforator. Machines are used in underground mines that are not dangerous for gas and dust in conditions of plus temperatures.
Necessary operating conditions:
— the compressed air supplied to the machine must be cleaned of mechanical impurities and water (air pollution is not lower than 10 pollution class according to GOST 17433), the pressure must be at least 0.5 MPa (5.0 kgf/cm2);
— ventilation of the mine must comply with the requirements of the «Uniform Safety Rules for the development of ore, non-metallic and placer deposits by underground method»
