复合支护技术在软岩段巷道中的应用

Combined Supports technology applied to the soft rock tunnel

本文针对花园煤矿开拓巷道中遇到的软岩具有松散破碎、高饱和吸水性、强膨胀性及流变性等的特点,分析研究了巷道支护失效的原因,在现场施工中采用了多种复合支护方式,保证了工程支护质量和施工安全,特别是在轨道大巷应用施工中取得了良好的支护效果。

According to the eharactefistles of the soft rock with the loose and brokon rock,the high saturated hygroscopicity, the strong expansibility and theological behavior and so on in the developing entry of the Huayuan Coal Mine,this paper analyzed and studied the failure reason of the tunnel supports, thus, many kinds of quite practical union supports are adopted in field construction, which had guaronteed the project supports quality and the construction security, and specially applied it to its Main Rail - tunnel which achieved good supporting effect.
