海洋文学话语场是在历时性上重新发现海洋文学书写中岛屿、历史以及“人-海”关系想象空间的理论建构。它包含两个方面:一是海洋意象的人学感知;二是海权观念的民族国家认同。“海岛写作”,作为最狭义的海洋文学内核,是指以海洋岛屿环境为基本的抒情与叙事本体,表现海岛历史文化变迁和岛民生存处境的文学作品。海岛写作存在“向陆”“向人”“向海”三种文学向度,需要处理不同的主体面相,在历史书写和人学表现方面建构起海洋文学的主体性,探寻新的意义图景。海南海岛写作较有影响力的地方史传《海南岛传》、小说《岛》、口述史《风从南洋来》,体现出各自的文学主体性,极具代表性地显示了海岛写作独特的文学文体学价值。

为解决沿空巷道窄煤柱围岩控制难题,综合应用了理论分析、数值模拟、工程应用等方法,揭示了沿空巷道窄煤柱变形失稳机理,当煤柱尺寸较小时,煤柱内部煤体近乎进入残余破坏阶段,采动应力大部分转移至开采帮侧煤体内部,当护巷煤柱尺寸较大时,护巷煤柱表现出良好的承载性能,导致转移至开采帮侧煤壁内的采动应力有所减小,基于此,确定110505轨道顺槽采用切顶护巷协同支护技术,现场应用后,试验顺槽围岩整体可控,实现了沿空巷道110505轨道顺槽的稳定控制。
