【摘要】：賀西煤礦綜采工作面回采過(guò)程中瓦斯涌出量大,嚴(yán)重威脅礦井安全生產(chǎn)。首先,理論分析了回采工作面采空區(qū)瓦斯分布和運(yùn)移規(guī)律,采場(chǎng)礦山壓力與裂隙演化規(guī)律,瓦斯富集區(qū)分布特征,瓦斯鉆孔或巷道布置等。其次,測(cè)定了3303工作面所在煤層的瓦斯壓力、瓦斯含量、煤層透氣性系數(shù)、鉆孔瓦斯衰減系數(shù)等瓦斯參數(shù)；在分析了傳統(tǒng)的回采工作面Y型通風(fēng)方式優(yōu)缺點(diǎn)的基礎(chǔ)上,提出并實(shí)踐了Y+L的通風(fēng)方式；總結(jié)了目前高瓦斯礦井瓦斯抽采的各種方法,并在賀西煤礦3303綜采工作面實(shí)施了本煤層抽采,鄰近層裂隙帶抽采和采空區(qū)埋管抽采相結(jié)合的綜合瓦斯抽采方法。結(jié)果表明：賀西煤礦3303工作面所采煤層屬于高瓦斯可抽采煤層；Y+L的通風(fēng)方式,使得工作面各處的瓦斯?jié)舛鹊玫接行Э刂?杜絕了瓦斯超限；多種瓦斯抽采技術(shù)綜合應(yīng)用和實(shí)施,明顯降低了工作面及總回風(fēng)巷的瓦斯?jié)舛?保障了工作面的安全回采。
[Abstract]:The large amount of gas emission in the mining process of fully mechanized mining face in Hexi Coal Mine seriously threatens the safety of mine production. Firstly, the distribution and migration law of gas in goaf of mining face, the evolution law of pressure and fissure in stope, the distribution characteristics of gas accumulation area, the arrangement of gas borehole or roadway are analyzed theoretically. Secondly, the gas parameters such as gas pressure, gas content, permeability coefficient of coal seam and gas attenuation coefficient of borehole in 3303 coal face are measured, and the advantages and disadvantages of traditional Y-type ventilation mode in mining face are analyzed. This paper puts forward and practices the ventilation mode of YL, summarizes the various methods of gas drainage in high gas mine at present, and implements this coal seam drainage in 3303 fully mechanized mining face of Hexi Coal Mine. A comprehensive gas extraction method combined with underground pipe extraction in goaf and adjacent fissure zone. The results show that the coal seam in 3303 face of Hexi Coal Mine belongs to the ventilation mode of high gas draining coal seam, which can effectively control the gas concentration in all parts of the coal face and put an end to the gas over-limit. The comprehensive application and implementation of various gas drainage techniques can obviously reduce the gas concentration in the working face and the total return air roadway and ensure the safe mining of the working face.
