煤炭自燃的条件之一是由于采空区或煤柱裂隙中存在着长期连续的漏风。要减少这种漏风有两个途径:一是在所有漏风通道上构筑高质量的密闭墙;二是设法减少漏风通道两端的风压差,前者是过去的传统做法。但是俗话说:“没有不透风的墙”。无论多么严密的密闭墙,只要存在风压差,漏风就不可避免,只是随着密闭质量有提高其漏风量相应减少而已。因此,很久以来人门都在 One of the conditions for coal spontaneous combustion is due to the long-term continuous air leakage in the cracks in the goaf or coal pillar. There are two ways to reduce such air leakage: one is to construct a high-quality confined wall on all air leakage channels; and the other is to try to reduce the pressure difference between the two ends of the air leakage channel. The former is the traditional practice of the past. But as the saying goes: “There is no airless wall.” No matter how tight the confined wall, as long as there is poor pressure, air leakage is inevitable, but as the quality of hermeneutic increased its air leakage reduced accordingly. Therefore, people have been here for a long time
