摘　　要：煤矿环境中,矿工在狭窄坑道出口处人体电容迅速降低至原来电容的十分之一,人体动态电压会增加十几倍,容易成为瓦斯燃爆的点火源.通过对人体静电泄漏规律的分析得出:静电半衰期主要与介质的电阻率有关.通过人体静电放电模拟引爆瓦斯的实验,获得了不同的人体电容、放电间隙和瓦斯体积分数与瓦斯爆炸之间的关联.Human body capacitance of miners decreases quickly to one tenth while body moving voltage increases up to a dozen times at the narrow exit in the coal mine , which is easy to be a source to detonate the gas. The study of the electrostatic bleeding rules of human body shows that the electrostatic half-life is relative with the material resistivity. From a series of simulation experiments of the gas exploded by human body electrostatic discharge, the relationship between different human body capacitance, discharge gap, gas concentration and gas explosion is obtained.
