在苏联第十二个五年计划期间,为了加速巷道掘进的科学技术进步,有关科研、设计、制造厂集中力量研制技术水平更高、质量更好的掘进机械,以保证掘进工作的高度机械化和减少手工作业量。 为增加掘进机掘进工程量,正在对四种掘进机改型,并研制五种新型掘进机。1986年雅西诺瓦机械制造厂已开始批量生产改型的4ΠΠ-2M型掘进机,该机由工厂与中央地下机械研究院共同研制,与4ΠΠ-2型掘进机相比,改型后掘进机的工作机构装有带PKC-2和PΠΠ-2M型截齿的两个截割头,掘进机的传动装置功率由105增大120kW.掘进机可沿煤层掘进,并可在f≤6的岩石占工作面面积75%或f=7的岩石占工作面面积15%时,进行破岩掘进。
During the twelfth five-year plan of the Soviet Union, in order to speed up the scientific and technical progress of roadway driving, relevant scientific research, design and manufacturing factories concentrated their efforts on the development of tunneling machinery of higher technical quality and better quality so as to ensure a high degree of mechanization of the driving work and Reduce the amount of manual work. In order to increase the amount of boring machine driving, four types of boring machines are being modified and five new boring machines are being developed. 1986 Ixia Nova machinery factory has begun mass production of modified 4ΠΠ-2M boring machine, the machine by the factory and the Central Underground Machinery Research Institute jointly developed, and 4ΠΠ-2 boring machine compared to retrofit after heading The working mechanism of the machine is equipped with two cutting heads with PKC-2 and PΠΠ-2M picks and the power of the drive of the boring machine is increased by 120kW from 105. The boring machine can be driven along the coal seam and can be operated at f≤6 Broken rock excavation is carried out with rocks accounting for 75% of the face area or f = 7 rocks occupying 15% of the face area.
