American coal mining equipment manufacturer Long-Airdox, will spotlight its latest Fletcher roof-bolter designs and newly developed automation systems for its Full Dimension continuous haulage equipment at the MINExpo show in Las Vegas in October.

Long-Airdox has also made its first Jeffrey continuous miner sale in Australia since acquisition of Jeffrey Mining Products in mid-1999.
