云南老厂多煤层渗透率和等温吸附特征对开发层系优选

Optimal Selection of Development Strains by Multi-bed Permeability and Isothermal Adsorption Characteristics in Laochang Yunnan Province

研究区位于滇东黔西地区,发育20~53套煤层,属于典型的多煤层发育区,为了能优选主力开发层系,探讨了多煤层渗透率和等温吸附特征,C16煤渗透率最大,C7+8、C19煤渗透率次之,C13煤渗透率最小;C16煤吸附性最好,C19煤次之,结果表明C16、C19两套煤层作为重点勘探层系,C7+8(C7)、C13煤作为第二梯队接替层系。

The area is located in western Yunnan,with 20~ and 53 sets of coal seams,which belong to the typical multi-coal strata development area. In order to select the main development strata,the permeability and isothermal adsorption characteristics of multi-coal seams are discussed. Coal seam 7+8,coal seam 19 permeability,coal seam 13 permeability is the smallest;coal seam 16 adsorption is the best,coal seam 19 is the second,the results show that coal seam 16,coal seam 19 two sets of coal as the key exploration strata,coal seam 7+8,coal seam 13 as the second echelon succession system.
