1977年8月在北票矿务局召开的北票煤田煤层瓦斯组份与突出关系的评议会,得出了在北票条件下,突出区域的重烃(C_4°～C_8°)含量可达1%(体积比),非突出区重烃含量低于1%,突出煤层与非突出煤层比较,重烃含量有明显差异的规律。这个规律是否具有普遍性,是对今后予测煤层区域性突出和探讨突出机理都具有一定意义的。为此我们对湖南红卫煤矿的突出井口(坦家冲工区)及非突出井口(龙家山工区),以及
In August 1977 at the Beipiao Coal Mine Bureau held a coal seam gas composition and prominent relationship between the Council, concluded that under the conditions of the North vote, the prominent areas of heavy hydrocarbons (C_4 ° ~ C_8 °) content up 1% by volume, heavy hydrocarbon content less than 1% in non-salient areas, and significant differences in heavy hydrocarbon content between salient and non-salient coal seams. Whether this law is universal or not is of great significance to the regional prediction of prominent coal seams and the exploration of outstanding mechanisms. To this end, we highlight the prominent wellhead (Tanjiachong mining area) and the non-prominent wellhead (Longjianshan area) of Hongwei Coalmine in Hunan, as well as
