为了探讨高沼气多风井复杂通风系统的矿井进行反风的可行性,焦家寨矿于1987年5月1日进行了一次全矿井全系统的反风试验。历时3小时37分。反风效率达到83%。(中采区达到90.2%,西采区达到84.6%)。反风设施安全可靠,达到了《煤矿安全规程》规定的要求。这次试验是轩岗建矿33年来多风井高沼气矿反风试验的首次尝试。此次反风试验的成功,为今后抢险救灾提供了可靠的第一手资料。
In order to investigate the feasibility of anti-wind mine in complex ventilation system with high biogas multi-wind well, Jiaojiazhai Mine conducted a total system wind-attack test on May 1, 1987. Lasted 3 hours 37 minutes. Wind efficiency reached 83%. (90.2% in the mining area, 84.6% in the west mining area). The anti-wind facilities are safe and reliable, reaching the requirements stipulated in “Coal Mine Safety Regulations”. This test is the first attempt of anti-wind test for multi-shaft high-methane gas mine in Xuan Gang Mine in the past 33 years. The success of the anti-wind test provided reliable first-hand information for future disaster relief.
