Abstract

Abstract: According to problems of thick coal seam, passing old roadways and stress concentration. The design of using old gateways for new longwall face was conducted. Exploiting coal reserve in difficulty strata by thick longwall can be achieved by driving new gateways in stress release area and enhance roof supporting and fire proof measures.

Key words: outburst seam, thick seam, longwall, pillar, optimization design
