Mining technology with stagger roadway in pillarless districts in fully-mechanized sublevel caving face of deep mine and goaf internal misaligned layout
Aiming at the problem that in fully-mechanized sublevel caving face of deep well, the rockburst in roadway internal goaf is difficult to control and the roadway is difficult to support, this paper presents a mining technology with stagger roadways and goaf internal misaligned layout, which consists of the supporting technology in high-grade conventional mining reasonable, the technology of adjust the gradient of face gently and fire-protection technique in working-face. According to field measurement, the t...
