Natural Energy Autonomous House with Underground Water Reservoir

Metagenome of the Siberian Underground Water Reservoir

We report on the metagenome of a deep subsurface aquifer in the Tomsk region of Russia, sampled via an oil exploration borehole drilled to a depth of 2.8 km. Methanogenic archaea were present in the water along with members of various bacterial phyla, including Firmicutes, Chloroflexi, Bacteroidetes, Ignavibacteriae, and uncultured candidate divisions.

Safety distance between underground natural gas and water pipeline facilities

A leaking water pipe bursting high pressure water jet in the soil will create slurry erosion which will eventually erode the adjacent natural gas pipe, thus causing its failure. The standard 300 mm safety distance used to place natural gas pipe away from water pipeline facilities needs to be reviewed to consider accidental damage and provide safety cushion to the natural gas pipe. This paper pr...

Experiments in autonomous underground guidance

This paper presents the results of an experimental program for evaluating sensors and sensing technologies in an underground mining applications. The objective of the experiments is to infer what combinations of sensors will provide reliable navigation systems for autonomous vehicles operating in a harsh underground environment. Results from a wide range of sensors are presented and analysed. C...

Percolation Approach in Underground Reservoir Modeling

positioning underground reservoir by underground dams by using geoelectric method

today, saving and storing water are among the most critical and important issues which have attracted the world's attention. history of storing water in the form of ghanat and water reservoir by iranians goes back to ancient times. studies on this field show that benefiting from underground dams was one of the methods employed for exploiting water in past times. in countries like iran, due...
