Using the technology evaluation principle in TRIZ (theory of inventive problem solving) theory as a powerful tool, combined with consumer psychology and relevant knowledge on products modeling methodology, evolution patterns and evolution paths of electronic consuming products figures have been explored. Moreover a set of regulations working for figures innovation design is established.展开更多

Concerning the longwall mining in China, the "masonry beam theory"(MBT) was first proposed in the 1960 s, illustrating that the transmission and equilibrium method of overburden pressure using reserved coal pillar in mined-out areas can be realized. This forms the so-called "121mining method", which lays a solid foundation for development of mining science and technology in China. The "transfer rock beam theory"(TRBT) proposed in the 1980 s gives a further understanding for the transmission path of stope overburden pressure and pressure distribution in high-stress areas. In this regard, the advanced 121 mining method was proposed with smaller coal pillar for excavation design,making significant contributions to improvement of the coal recovery rate in that era. In the 21 st century,the traditional mining technologies faced great challenges and, under the theoretical developments pioneered by Profs. Minggao Qian and Zhenqi Song, the "cutting cantilever beam theory"(CCBT) was proposed in 2008. After that the 110 mining method is formulated subsequently, namely one stope face,after the first mining cycle, needs one advanced gateway excavation, while the other one is automatically formed during the last mining cycle without coal pillars left in the mining area. This method can be implemented using the CCBT by incorporating the key technologies, including the directional presplitting roof cutting, constant resistance and large deformation(CRLD) bolt/anchor supporting system with negative Poisson's ratio(NPR) effect material, and remote real-time monitoring technology. The CCBT and 110 mining method will provide the theoretical and technical basis for the development of mining industry in China.展开更多
