  • Research on Non-Pillar Coal Mining for Thick and Hard

    Jan 07 2021 · This article introduces a new non-pillar coal mining technology (i.e. Gob-side Entry Retaining by Roof Cutting (GERRC)) under the condition of thick and hard roofs. First we theoretically analyzed the solution to the large suspension span of the thick and hard roof in coal mining. Three-Zone pre-split blasting design in non-pillar coal mining for thick and hard roofs

  • VentilationBasic Mining Process underground COAL

    A small quantity of air may flow through mine workings naturally but this would be insufficient and uncontrolled and therefore it is necessary to provide a mechanical means of ventilating the mine. To do this at least two connections between seam and surface are required and large fans are connected to one of these.
