Technical Analysis of Coal Mining Bow Flexible Shield Support for Roadway Retention along Goaf
Taking the large inclination coal seam of 3062 working face in Shanxi A Mine as an example,the technology scheme of retaining roadway along goaf with bow flexible shield was designed.Firstly,the basic situation of large inclination coal seam was introduced,based on which the design content and installation process of bow flexible shield were analyzed,and the stress of bow flexible shield was discussed according to the characteristics of large inclination coal seam;secondly,the application effect of the technology was verified by case analysis;finally,it was determined that the stability of the roof and floor of coal seam can be improved and the deformation can be reduced,which is conducive to the development of coal mining.
