Research and Practice on the Technology of Anchor Net Support in Coal Roadway
Abstract: Coal tunnels are mainly supported in shed stent, anchor net, anchor cable, anchor injection, etc. Under complex geological conditions of support, the safety or not is often difficult to get to pre- judge. Combined with the actual situation of Baodian Mine, from the construction of modern in-formation technology requirements, a need to study the stability of surrounding rock of the early warning system is determined to achieve pre-determination of the steady state of roadway sur-rounding rock. Using anti-analysis theory to anti-inverse mechanics characteristic parameter of the roadway rock mass, combined with theoretical calculations and numerical analysis software to obtain specific indicators and parameters to determine the roadway of surrounding rock stability, and combined with the displacement of the roadway to be pre-judged, stress and roof separation monitoring data, it is possible to use the actual production status roadway surrounding rock which is determined in advance, enabling coal roadway safety support.
