and has been influenced by such processes in one way or another. 2. History The German folk saying has stated for ages that a steady drop of water can drill a hole in a stone. The real life appliions of pressurized water date back to the 19th century, when Californian gold miners of the 1870's used it to remove layers of sand and rock.
· Abstract. To study signal characteristics of precursory infrasound of granite failure, coalrock stress loading device and infrasound acquisition device were adopted to perform infrasound test in uniaxial loading process for granite samples. Wavelet filtering, infrasonic energy methods were used to process and analyze the test results.

· Abstract. The destruction of the rock that surrounds boreholes under thermohydromechanical coupling is an important factor for borehole stability in hot dry rock (HDR) geothermal energy extraction. Failure experiments for granite under triaxial stress () were conducted as 500°C superheated steam was transported through the borehole.

Sankey diagrams are ideal for visually representing energy balances. This is because an energy balance represents the contribution and flow of various energy commodities (fuels, heat and electricity, energy carriers in a marketable form) into the different sectors of the economy ( supply, transformation and consumption) in energy units.
Basalt is a major rock type that occurs in virtually every tectonic setting. Basalt is clearly the most common volcanic rock on Earth and basaltic rocks (including gabbro, diabase and their metamorphosed equivalents) are the most common rocks in the crust is also common on the Moon and other rocky planets of the Solar System.
