| 摘 要： | 实体煤帮的高支承压力是影响沿空掘巷稳定性的主要原因之一。在分析了沿空掘巷应力环境的基础上,应用损伤理论,分析了给定变形下沿空掘巷实体煤帮的支承压力分布,并探讨了支承压力分布与煤岩厚度、弹性模量等参数的关系,对沿空巷道的维护与底鼓机理及控制的研究具有重要意义。

| Abstract: | The high abutment pressure on the integrated coal beside the roadway is one of the reasons to lead to floor heave and affect the stability of the roadway driving along next goaf . On the basis of analyzing stress situation of the roadway,the abutment pressure distribution of the integrated coal beside the roadway under given deformation is studied by damage theory. And the relationship between abutment pressure distribution and some parameters such as the thickness of immediate roof and coal seam,the elastic modulus of the strata,is analyzed. The presented result is important for the study of heave mechanism and control. |
