摘要/Abstract

摘要： 为研究掘进机扰动作用下超前支架动态响应特性,基于块系覆岩理论,构造超前支架-顶板耦合动力学模型,根据截齿截割阻力经验公式和牵引阻力经验公式推导截割头竖向受力公式,将其作为掘进机扰动激励,进行超前支架扰动作用下支架动态响应仿真与试验分析。结果表明:当超前支架-顶板接触刚度与超前支架支护刚度分别增加到2.5×10⁶kg/s²时,超前支架与顶板的位移幅值分别减小了66.78%和54.73%、58.91%和63.78%;当接触刚度增大至临界值1.5×10⁶kg/s²后,其对顶板位移变化量抑制作用减小。结果说明增加接触刚度或支护刚度均可减小掘进机扰动对超前支架的影响;当接触刚度达到某一临界值,顶板下沉量将趋于稳定。

Abstract: To study the dynamic response characteristics of the advanced support under the disturbance of roadheader, based on the theory of overburden strata, a coupled dynamic model was built for advanced support and roof rock. According to empirical formulas of cutting resistance of cutting teeth and traction resistance, a formula was deduced of for vertical force on the cutting head, which was taken as the disturbance excitation of roadheader. Dynamic response simulations and experimental analysis of advanced support were carried out under the above disturbance. The contact stiffness of the advanced support roof and the support stiffness of the advanced support were increased to 2.5×10⁶ kg/s² respectively. That resulted in that the displacement amplitudes of the front and top plates were reduced by 66.78% and 54.73%, 58.91% and 63.78% respectively. When the contact stiffness was increased to the critical value of 1.5×10⁶ kg/s², the vibration suppression of roof displacement decreases. It was found that increasing advance support and roof contact stiffness or advance support stiffness can reduce the effects of the disturbance on advanced support and roof rock displacement, and that roof rock subsidence would be stabilized when the forepoling-roof rock contact stiffness of the advanced support reaches a critical value.

Key words: advanced support, roadheader disturbance, roof rock, dynamic response, stiffness
