Pyongyang, June 23 (KCNA) — According to Rodong Sinmun, the machine-building industrial sector of the DPRK made a Korean-style efficient electric loader. This provided a guarantee for speeding up tunneling by giving precedence to earth-scraping in coal mines.

The new electric loader is higher in economic effectiveness than the pneumatic loader used in the past.

As it needs no compressor and air pipe, it is low in cost and can be used in any pit with less labour and material consumption.
