自动调压技术在综放工作面瓦斯治理中的应用

为了解决开滦(集团)唐山矿Y484工作面瓦斯涌出受地面大气压力变化影响问题，通过测定工作面通风阻力，找出地面大气压力变化与工作面瓦斯涌出变化之间的关系。依靠矿井监测系统，对地面大气压力及工作面瓦斯进行实时监测。根据监测数据研究开发一套能够实现自动控制的压力调节装置，确定了工作面自动调压治理瓦斯方案。结果表明，当地面大气压力及工作面瓦斯达到压力调节装置的预先设定值时，能够实现自动开启调压装置，从而达到抑制工作面采空区瓦斯涌出的目的，降低工作面瓦斯浓度，实现了矿井工作面的安全高效生产。

Research and application of auto-pressure-regulating technology in gas control of fully mechanized face

In view of the problem that the gas emission of Y484 working face of kailuan (group) co., LTD. Tangshan mining branch is affected by the change of surface atmospheric pressure, the ventilation resistance of working face is measured and analyzed, and the relationship between the change of surface atmospheric pressure and the gas emission of working face is analyzed. based on the calculation of ventilation network and ventilation pressure regulation, the reasonable position and area of regulating pressure of Y484 working face were found out. Relying on the mine monitoring system, the surface atmospheric pressure and working face gas are monitored in real time. According to the monitoring data, a set of pressure regulating device that can realize automatic control is developed. When the local atmospheric pressure and the gas on the working face reach the set value, the pressure regulating device can be automatically opened to achieve the purpose of restraining the gas gushing out of the goaf on the working face, reducing the gas concentration on the working face and realizing the safe and efficient production of the working face.
