Study on Transport Rules and Fully Mechanized Mining with Top Coal Caving Technology of Coal Seam with Huge Thickness in Tashan Mine

Article Preview

Abstract:

For the conditions of coal seam with huge thickness, structural complexity and intrusion by pyrolith in Datong carboniferous period, using laboratory similar simulation, on-site deep basis points observation and working face coal caving measurement, it is found out the migration and release laws of top coal, developed a practical caving technology. It has a good economic efficiency, and it is great significance for similar mining area to mining coal seam with huge thickness.
