Application of temporary support device in coal mine tunneling face
GUO Wen-xiao
Abstract：Due to strong labor requirements and great safe threatens arising from temporary support at tunneling face, temporary support device is adopted for support at working face. By using electronic automatic pressure recorder to measure and record the working resistance of temporary support device, we can acknowledge of the interaction between roof rock and temporary support device within the roadway and analysis characteristics of support devices, such as operation, reliability and adaptability. Hence, it demonstrated the reliable performance and good applicability of temporary support device at tunneling face.
