Roadheader A comprehensive review ScienceDirect

2020-1-1  The roadheader is a machine for excavating rock in mining and civil construction projects. It is a hybrid machine, with better manoeuvrability than that of tunnel boring machines. It can cut rocks even up to 160 MPa, if laminated or fractured, in different tunnel profiles and adapts easily to changing operational conditions.

Roadheaders Designed For Continuous Excavation

TON MR520 is an electrically powered, crawler-mounted roadheader designed for the production of potash and salt, with compressive strengths of 20–40 MPa (UCS).

ROADHEADERS PERFORMANCE OPTIMIZATION

2010-1-12  Roadheader performance and related parameters are reviewed and their effects on the production and which require high machine power and mass to react to these forces. Therefore, heavy duty hard rock machines with higher power and more mass have been developed and introduced into the market by manufacturers in recent years. The performance of a
