采空区漏风是形成煤矿井下自燃的重要因素之一,同时也是国内外煤炭通风研究领域中的重点课题。以山东兖州集团王庄煤矿7150工作面采空区为研究对象,建立了该采空区漏风特性的数学模型,按照实际情况绘制了物理模型及边界条件。利用计算机模拟程序对采空区流场及氧气浓度分布进行模拟分析,并验证了结果的有效性和准确性。本研究为井下采空区防火措施的制定提供了科学依据。 Air leakage in the goaf is one of the important factors in the formation of spontaneous combustion in coal mines. It is also a key issue in the field of coal ventilation research at home and abroad. Taking the goaf of 7150 face of Wangzhuang Coal Mine in Shandong Yanzhou Group as the research object, a mathematical model of the air leakage of the goaf was established. The physical model and the boundary conditions were drawn according to the actual situation. Computer simulation program was used to simulate the flow field and oxygen concentration in goaf, and the validity and accuracy of the results were verified. This study provides a scientific basis for the development of fire prevention measures in the underground goaf.
