In order to ensure the safety and efficiency of overfault mining in coal mining face,taking 5302 coal mining face crossing F101 reversed fault as the engineering research object,the technical scheme of coal mining face crossing fault and roof control measures were designed,and the engineering application was carried out.According to the mine conditions,the F101 reversed fault was recovered by using the scheme of rotating overdip crossing fault to reduce the quantity of rock mass cutting and improve the recovery rate of coal resources.At the same time,the roof was controlled by the combination of advanced pipe shed,flexible fiber mesh,constant resistance anchor cable and FRP trapezoidal beam.After field application,the advancing speed of 5302 coal mining face crossing F101 reverse fault was always maintained at 3.2 m/d,and the roof and coal wall remained stable,so the engineering application effect was remarkable.
