苏联采矿工业发展速度,要求在进一步改进和创制新型高效率凿岩机械和生产过程最大程度自动化的基础上,必须全力发展凿岩技术和提高凿岩效率。目前露天开采迫切需要高效率的钻机。认为压风排粉的滚轮凿岩是先进的方法,比钢绳冲击式穿孔效率高1-2倍。拟成批生产适于各种使用条件的三种(重、中重和轻型)滚轮钻机。指出滚轮凿岩效率在很大程
The development speed of mining industry in the Soviet Union demands that all efforts must be made to develop rock drilling technology and improve rock drilling efficiency based on the further improvement and creation of a new type of high efficiency rock drilling machinery and the maximum automation of the production process. At present, open-air mining urgently needs an efficient drilling rig. It is considered that the roller blasting of air pressure powder discharge is an advanced method, which is 1-2 times more efficient than the percussion punching of steel wire rope. Three (heavy, medium and light) roller drills are planned to be produced in batches suitable for various conditions of use. Pointed out that the wheel rock drilling efficiency is very large
