Vertical strain. Restricting ourselves to small deformations and stresses, several important material properties can be defined. For an isotropic, homogeneous material, there is a vertical deformation (ΔL) associated with the vertical stress. Normalizing this deformation by the original length of the sample, L, gives the vertical strain
Calculating vertical stress in the ground When a load is applied to soil, it is carried by the water in the pores as well as the solid grains. The increase in pressure within the porewater causes drainage (flow out of the soil), and the load is transferred to the solid grains.
The town of Gilman and nearby mining operations were developed in the 1880s by John Clinton, a prospector, judge, and speculator from nearby Red Cliff. In 1887, gold and silver were discovered in two vertical chimneys at the Ground Hog Mine, which continued to .
The new mining corporations developed extraction techniques that were frighteningly efficient, techniques that destroyed the rivers and caused California's first environmental disasters. Massive s lifted rock and sand--obliterating the formerly pristine rivers. The worst of the large scale mining techniques came in 1853 - hydraulic mining.

monitor settlement. In rare cases, guide casings can be installed in inclined boreholes where access is limited and prevents vertical installations in the preferred locations, or where the feature to be monitored is inclined. However, casing inclination is typically restricted to 30 degrees from vertical due to the potential for errors.

In 1840 settlers extracted 1,500 bushels of coal for local use. But because there were few steam powered engines or large institutions to provide the markets essential for the commercial development of coal mining, it would be almost 20 years before their needs spurred the commercial mining of coal.
