The Study of Combined Mining Technology at Thin Coal Seam with Hard Limestone Floor

Abstract:

The mining of thin coal seam with hard limestone floor require that the mating of full mechanized mining equipments must be scientific and rational.It is difficult to advancing when adopting inclined mining or the face meet geological structure. This paper analyzed and solved the main technical matters in the mining of thin coal seam with hard floor,such as fast marching method of inclined mining face ,process parameters optimization of mining face and meeting geological structure etc.
