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

Bin Yu, Jun Zhao

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.
