To study the influence of coal mining on the porosity of shallow sandy loam under conditions of shallow seam mining in thick, loose layers in northwest china, a typical surface sandy loam stratum in shaanxi province was taken as the study area, and experiments were performed to test the variation of soil porosity at different depths of 010 m in strata before, during and after mining therein.
Shallow soil geochemistry assays have currently been received on target zones 1, 2 and 3 on the ouassada permit.The nine linear gold shallow soil anomalies matched with structures present in the airborne magnetic data, and are very encouraging.
Tunnels and underground excavations tunnels and underground excavations tunneling techniques tunnels are generally grouped in four broad categories, depending on the material through which they pass soft ground, consisting of soil and very weak rock hard rock soft rock, such as shale, chalk, and friable sandstone and subaqueous.While these four broad types of ground condition.

The focus of soil mechanics is the understanding of soil behavior, construction with soils, on and in soils, the use of soils as construction material etc.Soil mechanics is a branch of civil engineering that has witnessed an enormous developement during the twentieth century.All aspects of soil mechanics and soil engineering are included in this section covering a wide range of engineering.
The method proved very simple and required less complex plant and equipment than normal when excavating the shallow soil sections in shafts.It involves driving steel sheets ahead of the shaft sump into the soils and then excavating inside the tub created by the sheets whilst supporting the sheets above with regularly spaced circular steel.
