摘要:

采用埋管技术对皖北煤电五沟煤矿CT101工作面采空区进行观测,获取了不同位置测点不同埋深时的温度、氧浓度等数据,通过对各测点温度及氧浓度的变化规律分析,确定了CT101工作面采空区自燃“三带”范围。同时对采空区温度场进行模拟,得出了该条件下采空区“三带”分布的一般规律,并对此种条件下“三带”分布的特殊情况及形成原因做出分析。

关键词: 充填开采, 沿空留巷, 采空区“三带”, 自燃规律

Abstract:

This paper gets the parameters of temperature and concentration of oxygen at different distances of different measuring points in mined-out area and air return lane by site buried tube observation in the gob of Wugou coal mine CT101 workface. Through analysis the change rule of temperature and oxygen concentration of each measuring point, determine the scope CT101 mined-out area spontaneous combustion "three zones". At the same time, using the method of numerical simulation, to simulate temperature field in mined-out area, obtained the general law of a "three zones" of the mined-out are.

Key words: mining with Filling, gob-side entry retained, the "three zones", of Mined-out area, the rule of spontaneous combustion
