【摘要】 随着开采深度的不断增加,巷道底鼓问题日趋严重。分析了采深对巷道底鼓的影响,以及自重应力、构造应力、围岩强度、地温、水随开采深度变化的规律。在此基础上,研究深部开采条件下巷道底鼓发生的机理,并对自重应力、构造应力、围岩强度、地温、水对底鼓的影响进行了分析。更多还原

【Abstract】 With the increase of mining depth, the problem of floor heave of roadway could become more and more serious. The thesis analyzes the effect of the increase of mining depth on the floor heave, discusses the laws that gravity stress, tectonic stress, the strength of surrounding rock, terrestrial heat and imbibition water change with the increase of mining depth. Basing on this, the paper researches the mechanism of floor heave, and analyzes the effects of gravity stress, tectonic stress, the strength of surrounding rock, terrestrial heat and imbibition water on floor heave.更多还原
