3412工作面区域防突技术措施

The Technical Measures of Anti Outburst in 3412 Face Area

对于具有煤与瓦斯突出危险性综采工作面,为杜绝工作面回采期间瓦斯涌出量大、瓦斯超限以及煤与瓦斯突出事故发生,工作面在回采前必须采取合理有效的防突技术措施。本文以新元矿3412工作面为例,对该工作面在回采过程中采取的区域防突措施进行研究,并对工作面采取区域防突措施后取得的效果进行检验分析,确保有效消除回采煤层瓦斯突出危险性。

With regard to the fully mechanized coal face with the danger of coal and gas outburst, to put an end to large amount of gas emission during mining face and gas overrun and coal and gas outburst accident, reasonable and effective technical outburst prevention measures must be taken face before stoping. In this paper the 3412 face, Xinyuan Mine, is taken as an example, the local outburst prevention measures taken in the process of mining were studied, and the effect after the test is also analyzed to ensure that the gas outburst fatality in the seam will be effectively reduced.
