综采工作面回采过程通风与瓦斯管理研究

Research of Ventilation and Gas Management in Fully Mechanized Face

针对综采工作面回采过程中的通风与瓦斯管理问题,本文以小常矿为例,首先介绍了工作面结构和瓦斯概括,然后分别从通风系统路线设计、需风量计算等角度研究了回采过程的通风管理,接着从回风上隅角瓦斯治理、瓦斯抽采钻场布置和瓦斯浓度监测等方面研究了回采过程的瓦斯管理措施。

Aiming at the problems of ventilation and gas management during the mining process in a comprehensive mechanized mining face,taking the Xiaochang coal as an example,first introduced the working face structure and gas summary,and then separately from the route of the ventilation system design,need air volume calculation of the ventilation management of mining process,and then studied the gas management measures in the stoping process from the aspects of gas control in the upper corner of the return air,gas extraction and drilling site arrangement and gas concentration monitoring.
