| 摘 要： | 官地矿煤层地质条件变化大,结构复杂,特别是南四采区的6#煤层(俗称7尺煤)起伏比较大,给开采带来了一定的困难.通过16403工作面上山开采时对工作面支护方式的研究,改变传统的移架方法,利用液压单体支柱配合移架,调整支架四连杆机构,使支架充分接顶,确保了项板的完整性,有效地提高了生产效率.

| Abstract: | Change of geological conditions of seam in Guandi coal mine is large,complex structure,especially in the southern district of the four-seam # 6(commonly known as 7 feet coal) more ups and downs,brings certain difficulties to the exploitation.Through study of supporting way to rise mining of 16,403 working face,changes the traditional moving support way,by using individual hydraulic prop to coordinate with moving support,adjusts four-bar linkage of support,causes the support to meet fully roof-contact,ensure... |
