小煤柱掘进巷道的施工技术探讨

小煤柱掘进巷道大多都存在于复杂的矿压环境之下,巷道的稳定和巷道的支护技术、煤矿工作面的尺寸有着比较紧密的联系。为了在最大程度上控制小煤柱的变形,对其变形机理进行了深入的研究,并取得了一定的效果。施工过程中的采掘接替紧张而造成的动压区会导致小煤柱巷道一定程度的变形和失稳,进而影响施工管理。所以要加强小煤柱掘进巷道的施工技术研究。

On the Construction Technology of Excavation Roadway with Small Coal Pillars

Most of the excavation roadways with small coal pillars are of complex mine pressure, and the stability of the roadway is closely related to the roadway support technology and the size of the coal face. In order to control the deformation of small coal pillars in the maximum extent, the deformation mechanism is studied in-depth and certain results has been achieved. Dynamic pressure area caused by intense mining - excavation relay during the construction will result in a certain degree of deformation and instability of the roadways with small coal pillars, and then affect the construction management. So the study on the construction technology of excavation roadway with small coal pillars should be strengthened.
