针对深井综放采场沿空区段巷道冲击地压难以控制、巷道支(维)护难度大问题.提出一种区段巷道内错采空区布置(简称负煤柱),并配套高档普采段合理支护技术、工作面平缓变坡技术和工作面防火技术.经过现场应用,该技术防治冲击地压效果显著,有效控制巷道变形,减小巷道支(维)护难度,有一定的应用价值.
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 technique for prevention of rockburst effect is remarkable. It can controls the roadway deformation effectively and reduce the difficult of supporting and maintenance of the roadway. This study It has certain application value.
