ABSTRACT OF THE DISCLOSURE The invention concerns a method of surface mining along an elongated pit using a cross-pit conveyor for trans- ferring selected excavated material, such as topsoil, directly across the pit while using a separate overburden excavator to transfer the remaining overburden. The method uses a cross-pit transporter which is supported solely on the working bank, includes a cantilevered conveyor which extends completely across the pit, and is slewable so it can periodically swing to a non- interfering position when passing the other excavator. The method allows the selective replacement of the different over- burden materials in accordance with modern reclamation practice.
