Published: August 2013

Three coals (Jincheng coal, Hancheng coal and Shan-bei coal) varying widely in coal type have been treated with anionic surfactant Sodium Dodecyl Sulphate (SDS). The effect of SDS on wettability of coals was explored by contact angles and zeta potentials characterisation techniques. Results obtained show that the addition of SDS can obviously improve the wettability of coals, and as the coal rank decreases, the wettability increases under investigation. Moreover, the wettability obviously increases with the significant decrease of particle size. The zeta potential for each coal, in the absence of surfactant, is negative, and the potential becomes more negative with the addition of SDS. Meanwhile, the FTIR spectrogram was used to test the changes of-COOH and-OH to analyze the reason for change of wettability, the results show that the wettability changes may be attributed to that the negative active ions of SDS are adsorbed on the coal surface, resulting in the increase of hydrophilic groups of the coal surface.

Risk Management of Induced Micro-Seismicity Caused by Hydraulic Fracturing through Acoustic Emission
Authors: Feng Yuan , Feng Chao Yin
Published: August 2013

To release the shale gas potential in China, hydraulic fracturing technologies play an important role. However, the latent technique risk deserves special attention. For example, the site-nearby micro-seismicity may have some relationship with the hydraulic fracturing. Nonetheless, the good news is that carbon dioxide stimulation can be used to displace hydraulic fracturing and obviate the potential earthquake risk. But the carbon dioxide methods are not economical nowadays, and hydraulic fracturing will continue to dominate. Through acoustic emission monitor, the reservoir characteristics and induced micro-seismicity magnitude and frequency will be collected and evaluated. Based on pre-existing project experience and numerical simulation, difference assessment standards about the hydraulic fracturing parameters are proposed to evaluate the micro-seismicity risk. Combined with other characteristics of rock property and fault location, this risk management can be used to guide the subsequent drilling and mining in practice.

Published: August 2013

Mechanical and deformation characteristics of pile-anchor retaining structure was analyzed by using numerical simulation method. The rationality of numerical model was also verified through comparing measured data in field test and numerical results. On the basis of this numerical model, Mechanical and deformation characteristics of pile-anchor retaining structure under three different construction procedures were analyzed individually. The results show that: the maximum horizontal displacement of pile is controlled effectively by applying anchoring force, and the global horizontal displacement of pile increases as well. Forced state of pile is changed from being bended on one side to being bended on both sides, and maximum moment value decreases heavily. Therefore, anchor cable reinforcement should be arranged at the head of construction procedure of pile-anchor retaining structure. The later anchoring force be applied, the closer inflection point nears the pile top.
