Analysis of the dialectical relation between top coal caving and coal-gas outbtu rst

According to the different engineering mechanical states of top coal caving andnormal stoping of gaseous loose thick coal seams,the dialectical relation between thiscaving method and dynamic disasters was analyzed by simulating the change of stressstates in the process of top coal initial caving with different mining and caving ratios basedon the ANSYS10.0.The variation of elastic energy and methane expansion energy duringfirst top coal caving was analyzed by first weighting and periodic weighting and combiningwith coal stress and deformation distribution of top coal normal stoping as well as positiveand negative examples in top coal caving of outburst coal seam.The research shows thatthe outburst risk increases along with the increase of the caving ratio in the initial miningstage.In the period of normal stoping,when the mining and caving ratio is smaller than1:3 and hard and massive overlying strata do not exist (periodic weighting is not obvious),it is beneficial to control ground stress leading type outburst.Thus,it is unreasonable toprohibit top coal caving in dangerous and outburst prone areas.

德法哲学转进融合的心身问题

现代德法哲学对心身问题的探讨经历了三个过程:传统的心身二元论被还原为纯粹意识与动感感觉的相关性,生存论与存在论在此相关性基础上激烈对峙,心身存在最终建基于超越者的原始肉身化中。尽管心身关系在原始的体验和存在层面不断获得重构和新的建基,但由于现象学与象征阐释学对形式化以及同一化的先行设定,致使它们一开始就错失了心身之自然生成的无限性,不再追问有限化之辩证状态的前提性,最终陷入了以形式化的主体性吞噬自然存在的困境。只有在人的自然本性与其身处的自然存在的本源统一中,人们才可能真正理解自然的抽象化以及由其所决定的心身存在。
