More Information
Summary:The invention discloses a high-burial-depth and small-spacing roadway group rock pillar load calculation method. The method comprises the steps of determining a collapse range, determining a collapse height, comprehensively considering the collapse height corrected by other factors, determining a collapse arch curve, calculating rock pillar loads, and determining the construction sizes of the rock pillars between the roadways according to the maximum loads, calculated in the fifth step, of the rock pillars between the roadways. Based on a traditional pressure arch theory and an optimized rock pillar load calculation formula, a high-burial-depth and small-spacing roadway group rock pillar load calculation formula is given, and the method can be directly used for designing the size of rock pillars between roadways according to the size of loads borne by the rock pillars; the calculation method provided by the invention is simple in formula and high in field operability, and has a certain application value. 本发明公
