The characteristic of in situ stress in outburst area of China

In order to obtain the characteristics of in situ stress field in outburst mining area, using the hollow inclusion (HI) technique to measure the in situ stress of coal and gas outburst mining area. The measurement sites located in northeast, middle and east of china, which include eight mining areas such as Fuxin, Pingdingshan, Hebi and Huainan. Base on the analysis of measurement data from outburst mining area, conclusions could be obtained as follow: (a) major principal stress and minor principal stress is horizontal stress and interim principal stress is vertical stress, and the type of outburst area’s stress field is dynamic stress field; (b) the major principal stress and minor principal stress are higher than other regions and the tectonic stress is outstanding; and (c) the ratio of major principal and vertical stress is decrease with the increase of depth and the type of stress field is likely transfer dynamic to static. Thus, in situ stress plays a key role during the occurring and development of coal and gas outburst, which is an important reason of severe outburst in China.     

Using game theory to describe strategy selection for environmental risk and carbon emissions reduction in the green supply chain

This paper provides an approach in the context of green supply chain management, using game theory to analyze the strategies selected by manufacturers to reduce life cycle environmental risk of materials and carbon emissions. Through the application of the ‘tolerability of risk’ concept, a basis for determining the extent of environmental risk and carbon emissions reduction has been established. Currently, scant attention is given to holistic supervision of the supply chain with respect to carbon emissions by governments, and thus the starting hypothesis here is that the default strategy that manufacturers will adopt is only to reduce carbon emissions, and thereby environmental risk, in so far as this is compatible with the aim of increasing revenue. Moreover, we further hypothesize that, once necessary governmental policy has been established in the supply chain management, the strategic choices of the manufacturers would be influenced by government penalties or incentives. A case example is provided to demonstrate the insight that indicates the application of game theory. The limitations of the game model and analysis are discussed, laying a foundation for further work.

循环流化床烟气悬浮脱硫技术中试及机理分析

设计了新的循环流化床烟气悬浮脱硫中试装置,其烟气处理量达3500m³/h.首先进行了进料钙硫比(Ca/S)、过饱和温度对装置脱硫效率影响实验,进一步研究了脱硫塔内固体颗粒物循环和烟气流速等因素对脱硫装置性能的影响.对比实验研究表明:在Ca/S=1.2时,固体颗粒物的循环使系统脱硫效率提高15% 左右;脱硫塔内烟气设计流速可以偏高一些.本文同时对系统脱硫过程进行了机理分析,指出了延长脱硫剂有效停留时间的途径.
