沿空巷道即位于采空区边缘和采空区内的巷道。按巷道与采空区的空间关系可分为三类:一类为沿空留巷;二类为典型的沿空掘巷即沿采空区边缘留1~4米的小煤柱掘巷;三类为在采空区内掘巷。 沿空巷道在生产中已引起人们的重视,但对它的适用条件论述较少。从目前应用的情况看,主要为一、二类。因此本文仅就徐州矿区沿空留巷和沿空掘巷的适用条件,谈一些粗浅看法。
Glade Roadway is located at the edge of the goaf and the gob of the roadway. According to the spatial relationship between roadway and goaf, it can be divided into three categories: one is for gob-side entry; the other is for typical gob-side entryway with 1 ~ 4m small coal pillar driving along the edge of goaf; Three types of roadway in the goaf. Roadway along the road in the production has attracted people’s attention, but its application conditions discussed less. From the current application of the situation, mainly for one or two categories. Therefore, this article only on Xuzhou mining area gob-side entry and roadway driving conditions for the application, to talk about some superficial view.
