摘要:
为了掌握高瓦斯沿空留巷采空区遗煤自燃危险区域分布规律,指导工作面防灭火工作。采用数值模拟的方法,以首次采用沿空留巷技术的乌兰矿工作面为实例,模拟分析采空区漏风及氧化带三维分布规律。使用单因素分析法,分别模拟高位钻孔、上隅角埋管及地面钻孔抽采对采空区氧气浓度分布的影响。结果表明:多种瓦斯抽采措施下,工作面及沿空留巷均向采空区漏风,导致氧化带范围扩大,但不同抽采措施导致氧化带扩大的程度不同,高位钻孔抽采最弱,上隅角瓦斯抽采次之,地面钻孔抽采最强。沿空留巷附近及上覆采空区供氧时间长,自然发火危险性高。
Abstract:
In order to master the distribution laws of spontaneous combustion dangerous zone for residual coal in goaf with high gas and gob-side entry retaining, and to guide the work of fire prevention and extinguishment at the working face, through taking the working face of Wulan coal mine with applying the technology of gob-side entry retaining for the first time as example, the three-dimensional distribution laws of air leakage and oxidation zone in goaf were simulated and analyzed with the method of numerical simulation. The influence of high level borehole, buried pipes at upper corner and surface borehole extraction on the distribution of oxygen concentration in goaf were simulated respectively by using the single factor analysis method. The results showed that under a variety of gas extraction measures, the air leakage will generate from both the working face and the gob-side entry retaining to the goaf, which will lead to the expansion of the oxidation zone range. The extent of oxidation zone expansion is different with different measures, that of high level borehole is the weakest, that of the buried pipes at upper corner is the second, and that of the surface borehole extraction is the strongest. The time of oxygen supply around the gob-side entry retaining and in the overlying goaf is long, so the risk of spontaneous combustion is high.
