Then i discussed methane desorption properties including cbm - bearing saturation, critical desorption pressure, the ratio between critical desorption pressure and original coal reservoirs pressure and difference of terra decompression ; cbm - bearing characteristics of coal seams including measured / academic cbm - bearing content, coalbed methane resources content and cbm resources abundance, etc. the author respectively gave a brief account of the basic characteristics of ancient and today ' s geothermic field at 1000m and 2000m depth, coal measure strata pressure field at the depth less than 1600m, structural stress field from jurassic to present, and ancient and today ' s fluid potential field ( that is water potential and gas potential distributing in coal measure strata )
分別簡述了準噶爾盆地1000m及2000m深度今古地溫場、 1600m以淺的煤系地層壓力場、侏羅紀至今地應力場及煤系地層水勢與氣勢分佈的今古流體勢場基本特徵，進而對這「四場」特徵及其互動關系與煤儲層物性、可采性及煤層氣聚集的關系進行了探討。從構造背景、構造演化及構造類型幾方面論述了本區構造作用的控氣特徵。 -
For the tectonic coal ， the properties of higher porosity and lower permeability make it capable of keeping higher gas pressure ； both of the “ isolating action ” and “ gas - cushion action ” cut down the resistance against outburst ； the specifity of high - defomed - extent makes desorption ， escape and flowing quickly become possible ； the existing of weak - seam or “ thoroughfare - seam ” create suitable conditions for the initial erupting and continued developing of coal and gas outburst. on the whole ， it is the synhesis action of all factors ， which leads to outbursts. the existing of tectonic coal with certain thickess is the essential condition of coal and gas outbursts ， but not the sufficient condition
高空隙率、低透氣性使構造煤能夠保持較高的瓦斯壓力；破碎性、 「隔離」作用及「氣墊」作用，使構造煤抵禦外力作用的能力大大降低；構造煤變形幅度大的特性，為瓦斯的迅速解吸、放散和快速流動創造了條件；構造煤薄弱分層或「通道層」的存在，則為煤與瓦斯突出的初始激發和持續發展奠定了基礎；上述因素的共同作用，影響和制約了煤與瓦斯突出的強度和分佈.盡管如此，一定厚度的構造煤的存在只是發生煤與瓦斯突出的必要條件和有利條件，而非充分條件 -
Through theoretical analysis, experiment on site and numerical simulation, the characteristic of goal - water - gas system was analyzed during injecting water, and the mechanics properties, stress and strain state of coal and quantity of gas emission were studied
摘要通過理論分析、現場實驗及數值模擬等手段，分析了注水過程中煤水瓦斯體系特徵，研究了注水對煤的力學性質、應力和變形狀態以及對瓦斯湧出量的影響。 -
