The Technology Research On Support In Two-roadway Of Coal Face In Banshi Coal Mine

The compressive strength of this article for Banshi mine roof and floor rock is relatively small, roof and floor rocks of low intensity and poor cementation, most of the mudstone and siltstone, more difficult to support soft-rock mines. Lead to a comprehensive and mechanized mining face very difficult the two crossheading support, especially by the dynamic pressure in the recovery period of deformation is large and difficult to maintain the smooth recovery of the working face of coal mining roadways After several renovated.For these reasons, in order to solve the mine working face support effect on the Slate coal mine working face of bolt support on the basis of survey research and field determination, Slate mine field data were measuredto determine the parameters of the support of the surrounding rock, and analysis to stress the size and direction of the roadway. The combination of theoretical analysis and numerical simulation experiments, research methods, analysis of the main factors affect the board stone coal face Roadway. Based on theoretical calculations, field tests and laboratory tests, Lane Slate coal face steel mesh and anchor support design theory suspended theory, given a fully mechanized coal face Roadway program, using computer simulation software support the rational design verification program; further adoption of the design implementation of the test roadway at the scene to show the correctness of the results of inspection and support design, rock pressure on the test roadway, and ultimately determine the supporting program to address the mine fully mechanized coal face two roadways support problems.
