Abstract

Deformation，fracture and instability of surrounding rock occur easily in expansive soft rock roadways due to its high clay mineral contents. Under the hydraulic action and high geostress，the clay minerals will show a strong hydrophilic expansibility and a weak resistance intensity. A case study combining with situ conditions of main haulage roadway in Xiaotun coal mine was performed. After geological surveys，field observations and laboratory tests，we find that the seepage action，weathering action，slaking durability and clay mineral contents all are reasons contributing to the deformation and instability of roadway surrounding rock. A combined support system of Full-closed steel grid frame + Wire mesh + Bolt + Shotcrete/Pouring concrete is put forward in this paper. The superiorities of the full-closed frame design are demonstrated，and the spacing between frames as well as the length of the bolts is optimized by numerical simulation. Meanwhile，catchpit is adopted to govern the water-inrush of roadway floor successfully. Finally，the full-closed steel grid frame-oriented combined support system effectively control the deformation of surrounding rock，therefore has a reference significance to similar expansive soft rock support engineering.

Key words： mining engineering steel grid frame full-closed soft rock roadway clay mineral inverted arch
