Xiaojihan Coal Mine 11215 fully mechanized working face secondary mining influence roadway advanced support scheme study

Abstract

Abstract:

Xiaojihan Coal Mine 11215 fully mechanized working face air return way was affected by the secondary mining. The roadway has different degrees of ceiling plate sank, floor plate plumped, two side wall deformation conditions, serious influence on the normal advance of fully mechanized working face. By analyzing mining pressure data, the advanced support scheme for 11215 fully mechanized working face air return way was indicated.

Key words:

coal, fully mechanized working face, secondary mining, mining pressure, support scheme
