Application of Weathering Protection at the Face

• Description:
  Many underground coal mines are composed of shale layered directly over the coal that weathers severely immediately after exposure to the mine atmosphere. Condensation of ventilating air causes underground coal mines to become wet during warm months; during cool months, the mines become dry from evaporation. The fluctuating mine atmosphere is responsible for the severe shale break-up experienced during the summer and lessening of the break-up through the winter months. The objective of this investigation was to design and construct spray equipment to be mounted on a continuous miner for sealing the mine roof immediately after exposure. Selection of the sealant and a field evaluation of the equipment is included. [Description provided by NIOSH]
