| 摘 要： | 近距离易自燃煤层群开采条件下,工作面与上部多层采空区、地表相互联通形成复杂的立体交叉漏风网,为防治多源点漏风引发的自燃火灾事故,进行多工作面风压动态调控分析,提出了多点调控反馈补偿整体平衡理论。建立了调控区域空间连通状态辨识模型,以多点动态调控系统的风压增益系数来描述各个调控区域的空间连通状态。同时,建立了多点动态调控系统的风压分布动力学方程,提出调控系统稳定性判别方法与系统反馈补偿整体调控方法,以达到多工作面风压整体动态平衡。

Theory of multipoint pressure balance in multilayer goaf by pressure feedback and compensation |
| |
| Abstract: | When mining the close coal seams with risk of spontaneous combustion，the working face interconnected with upper multilayer goaf and earth’s surface，and then stereoscopic cross air leakage network was formed.In order to prevent spontaneous mine fire caused by multi-source air leakage，the method of dynamic pressure regulation was analyzed for multi-face，and theory of multipoint pressure balance in multilayer goaf was put forward by pressure feedback and compensation.By identifying model of regulatory regions connected state，pressure gain coefficient was used to describe the connected state of various regulatory regions.With the dynamics equation of pressure distribution in dynamic multi-point regulation system，judging method was put forward for system stability.Through the pressure control method of feedback and compensation for various regulatory regions，multi-face pressure system would realize overall dynamic balance. |
