为了研究目前我国沿空留巷巷旁控制技术及其适用条件,笔者对150个沿空留巷巷道典型案例进行了分析,结果表明:目前主要应用的巷旁控制技术有高水材料充填、混凝土材料充填、膏体材料充填、块体类充填、矸石类充填、冒落矸石自然充填、切顶成旁支护技术等,其中高水材料充填、混凝土材料充填使用率最高;各巷旁控制技术的应用范围在煤层埋深、倾角、煤厚等3个地质条件上差别较大,在直接顶岩性和直接顶厚度上的差别较小。另外发现,高水材料充填、混凝土材料充填、膏体材料充填适用于深部及厚煤层条件,冒落矸石自然充填适用于大倾角、急倾斜条件。

in order to study the roadside conroltechnology of the gob-side entry retaining and the applicable conditons in China, an analysis was conducted on thetypical ases of 150 gobside entry retaning. The resut showed that the present appied roadside control technology could be dided to a high water materal backill oncrete bac .l. aste bac..imp material backl.cal refuse backlfaling waste rock natural ackill. of cuting backll nd other types and among them,.the igh water mateial backill and concrete backil had the highest utilization rate.The appication scope of each gateway roadside contrl technodogy woud have big diferencein thee coal contions of the sean depth intlination and thickn-ess and woult have less diference n the inmediate rof lithology and thickress Aiso the practices found that the high water mateial bacil.concrete backill and paste backilcould be applied under the deep mine and thick seam conitions and the fa赳ing rock waste atural backfill could be applied under the high inclination and steep inclination conditions.
