综掘工作面压入式通风粉尘分布规律实验
|
摘要
为掌握综掘工作面压入式通风粉尘的浓度分布规律,利用相似模拟方法模拟河南某矿21007工作面,设计一个模拟实验装置,通风方式采用压入式通风,在实验装置中布置测点,分析工作面不同位置粉尘的分布规律.结果表明:工作面回风侧的粉尘浓度明显高于中部空间和进风侧,粉煤尘是煤矿岩尘和煤尘的统称,粉尘危害是煤矿的重大危害之一.随着煤矿采掘机械化程度的提高,产尘量也剧增,粉尘治理的好坏直接关系到煤矿的安全生产,关系到矿工的身体健康.
In order to grasp the concentration distribution law of press-in ventilation dust in comprehensive excavation workface,a similar simulation method is used to simulate the 21007 working face of a mine in Henan Province,and a simulation experiment device is designed. The ventilation method is carried out by press-in ventilation,and the test point is arranged in the experimental device to analyze the distribution of dust at different locations on the working surface. Results show that the dust concentration on the return side of the working face is significantly higher than that in the middle space and the inlet side. Coal dust is the collective name of rock dust and coal dust. Dust hazard is one of the major hazards of coal mines. With the improvement of mechanization of coal mining,the amount of dust generated has also increased dramatically. The quality of dust control is directly related to the safe production of coal mines and to the health of miners.
