Abstract

Taking machinery roadway, ventilation passage of Roadway 8203 of Guobei Mine in Huaibei Mining Group as the research background, applying basic theory of modern solid mechanics, interaction mechanism between metal bracket and bolt were studied in the condition of large loose circle, high ground pressure soft-rock roadway. Several key technologies of extremely loose and extra thick coal seam in supporting overall along goaf roadway were introduced in detailed. The functional mechanism of key technologies was not only ana-lyzed in detail, but also on-site industrial tests were conducted. Good action effect of bolt and double re-sistant cloth was demonstrated in roadway of extremely loose coal seam, emphasizing the comprehensive ef-fect of the composite support structure "metal bracket + bolt + double resistant cloth". On the one hand, the research results provided a significant effect, low-cost rock support technology; on the other hand, it also fur-ther improved the support theory of rock roadway. It has certain reference value for roadway supporting de-sign in any case. It made the adjacent two mining areas into one and produced enormous economic benefits.
