中文摘要：

针对深部软岩底板煤巷沿空留巷底鼓流变、非线性大变形特征，通过理论分析、现场实测、试验等综合研究方法，对深部软岩底板沿空留巷底鼓特征、力源进行了分析，研究认为深部沿空留巷充填体承载分为3个时期，变形主要分为4个阶段，深井沿空留巷底鼓力源主要包括充填体及实体煤的“压模效应”传递、基本顶回转产生的侧压力集中、采空区冒矸压实“泊松效应”、深部高构造应力，以及软岩膨胀压力；结合沿空留巷充填体承载历史和应力路径不同划分为4种复合底鼓类型：单一膨胀型底鼓（SE型）、挤压膨胀型复合底鼓（EEC型）、压曲膨胀型复合底鼓（CEC型）、挤压压曲膨胀型复合底鼓（ECEC型），其破坏形态多以拉破坏或拉剪破坏为主，这4种不同的底鼓类型在不同的阶段起到了主导作用。研究结果为深部沿空留巷底板控制提供了重要依据。

英文摘要：

In view of theology and nonlinear large deformation of floor heave of soft rock roadway along goa[ in deep mine, the characteristics and driving forces of floor heave of deep soft rock roadway along goal were analyzed by theoretical a- nalysis, field test, experiment and so on. It was considered that the load hearing of side filling hody of deep roadway along goal can be divided into 3 periods, the deformation couldbe mainly divided into 4 stages, the force sources of floor heave deep roadway along goal include ＂die effect＂ transfer, the lateral stress concentration caused by basic roof rotary, ＂Poisson effect＂ of goal gangue compaction, high tectonic stress in deep stratum, as well as the expansion pressure of soft rock. According to the bearing history and stress paths of side filling body of roadway along goal, floor heaves could be classed into 4 kinds of composite type, they are single ex- pansion （SE） type, extrusion-expansion composite （EEC） type, compression-expansion composite （CEC） type and ex- trusion-compression-expansion composite （ECEC） type, the other mainly are tensile failure or tensile shear failure, these 4 kinds of floor heave type played a leading role in different stages. The results of study provided important basis for floor controlling of deep roadway along goaf.
