薄煤层复合顶板“110工法”的实践应用研究

Study on Practice and Application of "110 Construction Method" for Composite Roof of Thin Coal Seam

以东瑞煤业2101综采工作面为案例,进行“110工法”的实践研究。对切顶卸压沿空留巷方案从施工工艺和巷道支护两方面进行了研究。结果表明:留巷段顶、底板无明显变形,留巷效果理想。

Taking the 2101 fully mechanized mining face of Dongrui Coal Industry as a case,the practical study of "110 construction method" is carried out.In this paper,the scheme of roof cutting and pressure relief and retaining roadway along goaf is studied from two aspects of construction technology and roadway support.The results show that the roof and floor of the retaining roadway section have no obvious deformation,and the effect of retaining roadway is ideal.
