大洋采矿气力提升特性的试验研究

试验表明，气力提升特性与提升管内三相流的流型紧密相关，只有当供气量足以使三相流的流型保持团状流、且Ｔａｙｌｏｒ泡（见正文）充分发展的条件下，才能达到最大的提升量和最高的提升效率。文中还着重对气力提升的最佳工况进行了探讨。得出不同运行条件下的一般规律。并建立了综合效率参数与空气表现体积率的经验关系。

Mechanical analysis on deformation of surrounding rock with road-in packing of gob-side entry retaining in fully-mechanized sub-level caving face

Based on the movement regularity of surrounding rock with road-in packing of gob-side entry retaining in fully-mechanized sub-level caving face (RPGERFCF), the mechanical model of its surrounding rock was established and the calculating formulas of the deformation of the roof, coal wall and filling body were attained. By the mechanical analysis to the deformation of the surrounding rock of RPGERFCF, the major factors influencing the deformation of the surrounding rock were found out and the technologic approaches reduced the deformation and enhanced the stability of the surrounding rock were put forward. Consequently, the scientific bases were provided for the stability control of the surrounding rock of RPGERFCF.
