摘要
合理、有效地根治采场瓦斯,防止采场瓦斯超限,是“八五”期间煤矿安全重点研究课题之一.本文根据采场瓦斯运移理论阐述了采场瓦斯超限的基本原因,论述了采场瓦斯根治的技术途径,并给出了在煤矿生产和科研实践中行之有效的根治方法.
The question of reasonably and effectively eradicating gas in stope and therefore preventing gas-exceed-limit phenomenon from occurring is one of the key research topics in mining safety during eighth 5-year plan period. Based on the theory of stope gas migration, this paper elaborates the foundamental reasons for gas-exceed-limit phenomenon. It discusses technical means of eradicating gas in stope, it also details the method of effectively eradicating gas both in mining production and in scientific research practice.
