This invention is a continuum of enabling technology applying prior patent applications to create and then sustain a planetary heavy construction, soil and water mining and refining using a nuclear power appliances infrastructure. The methods used within this invention provide capabilities to build a sustainable support environment for earth-like habitable complexes that will include buildings and maintenance facilities, living spaces, and office spaces focused on full scale commercial mining operations for He3, H.sub.2O and other strategic minerals and raw building materials.

A mining dumper having a power transmission system arranged for moving the mining dumper. The power transmission system includes at least one electric motor arranged for applying additional power for moving the mining dumper and at least one energy storing device for supplying electric energy to the electric motor. A method for intensifying a moving of the mining dumper is also provided.

An actuator mounting arrangement includes a mining machine having a frame and at least one mounting unit. The mounting unit includes a first mounting part having at partial recess for partially receiving a protuberance extending from an outer surface of the actuator, and a second mounting part having a recess for partially receiving the protuberance. The recesses face each other and form a support surface for the protuberance. Each of the first mounting part and the second mounting part has a through hole for receiving the actuator so that the first mounting part and the second mounting part encircle the actuator in a plane transverse of an axis of the actuator in a mounted state. The first mounting part and the second mounting part have matching holes for mounting bolts with which the first mounting part and the second mounting part are detachably mounted together.

Apparatus and methods are described for excavating earthen material with millimeter-wave (MMW) radiation or a combination of MMW radiation and mechanical apparatus. The MMW radiation can reduce costs and hazards associated with excavation using mechanical means only and/or explosives. MMW-assisted excavation has significant energy advantages over optical or long-wavelength microwave excavation techniques.

The present invention is a relatively narrow tool carrying self-propelled machine that is particularly configured such that it can easily move through narrow mines while supporting any one of several tools. In one embodiment, the self-propelled machine is designed to be powered totally or substantially totally by an emulsion fluid that is readily available in mines.
