The problem of low digging efficiency and mining imbalance due to outdated technology degree equipment intelligence has long existed in coal mine roadway excavation work. Lithology identification is the key roadheading equipment. Accurate lithology significantly affects automatic control roadheader cutting conditions. Completing process rock wall by a involved following steps: building tunnelin...

The yielding arch support is transported and installed in the face with use of auxiliary machines. These activities underground mining cause many problems, which have as yet not been solved. Currently, transport assembly are carried out manually, using roadheader suspended rail, or various types mounting platforms. analysis structure existing solutions resulted development an original that met ...

This paper presents finite element analysis of the strength of roadheaher conical picks. Failure forms of conical picks are investigated, and the FE model of conical pick is established which is based on ANSYS. The static analysis is carried out according to the load calculated by empirical formula and the deformation map and stress distribution is obtained. The results show that the maximum st...
