To make the back-up trailers small enough relatively to boring diameter to gain some space in case of unexpectedly high ground deformations in the back-up area. 

Using sorts of mineral resources as basis to classify, there can be four types coal, mental, soil and gas, as well as building material. Besides ground deformation, solid waste occupation, water and soil pollution and secondary disasters, some special and representative mine environment geological problems of all sorts of mineral resources are all concluded below. 

Compared with the initial state, the settlement at observation point can be measured by using Trimble DiNiOS and summarized in Table 2. It is shown that the ground deformation over tunnels is more remarkable than the other. The maximum value is 8.7 mm (<10.0 mm), which is much similar to the one of numerical simulation. In other words, both the validity of numerical simulation method and the safety of construction design are verified powerfully. 

According to historical records and recent filed investigations, the most common type is disaster of slope instability, and secondary is the disaster of liquefaction and ground deformation, and third is the disaster of surface rupture and earthquake collapse. 

The disaster of liquefaction and ground deformation (seismic subsidence) is mainly in the river terraces, river deltas, alluvial plains and... 

The types of GDIE in China are plentiful and various and among them, the main types are slope instability, surface rupture, sand Liquefaction, debris flow and ground deformation, and secondary are collapses by seismic and barrier lake induced by earthquake with overflow, and seismic surge wave, tsunami and reservoir induced earthquake are rare types in China.

In case of line-like components, as the fourth component of Figure 1, corresponding to node TI4, there is more structure we have in this case a variable corresponding to peak ground deformation, i.e. Sg, that is children of node S s4 and, together with node OpA they are the parents of node A4 (rate of failures per unit length). The parents of D4 are the nodes Nla and B4 that are children of node A4. 

In this chapter we discuss the basic features of deformed structures in liquid crystals with chiral order. The characteristic scale of these deformations has to be compared to the scale p of ground deformations. Properties of defects and deformations that occur at scales smaller and larger than p are quite different.

Infrastructure risk can also be assessed for earthquake-induced ground deformation hazard such as liquefaction or lateral spreading, although this is less common since the prediction of permanent ground deformation is more complex. There are very few predictive relationships for...
