摘要

用沿空留巷技术保留的巷道要经历掘进和两次强烈的采动影响，对所需留巷的巷道，应该从掘进期间的支护设计与施工到留巷期间的巷旁支护方式选择，及下个工作面回采期间的加强支护均应统筹考虑，这样才能保证沿空留巷技术的成功实施，故沿空留巷技术是一项系统工程。据此，在淮北岱河矿Ⅲ3215工作面机巷进行了沿空留巷实践，巷内采用了锚网索支护，巷旁采用了工字钢密集支柱及矸石（碎煤）带联合支护，并在矿压观测的基础上，得出了所留巷道矿压显现规律，工业试验和应用实践表明，取得了良好的技术、经济效果。

Abstract

The maintained roadway by applying gob-side entry retaining technique will undergo the impact of excavation and two-time intensive mining. In order to insure to apply gob-side entry retaining technique successfully

some factors that include the supporting design and construction during excavating

the selection of roadside supporting way during retaining the roadway and the reinforced supporting method during actual mining of next working face should been systematically taken into account for the roadway which needs retaining. So the gob-side entry retaining technique is a systems engineering. According to this point

a test of gob-side entry retaining technique has been practised in transportation roadways of No. Ⅲ3215 working face in Daihe Coal Mine

Huaibei Mining Group Corporation. It is used bolt-mesh-cable support in the roadway

dense I-steel pillar and gangue or broken coal wall support roadside. The ground pressure behavior regularity of retaining roadway were obtained based on the ground pressure observation. Industrial test and application practice show that the good tech-economic effect has been achieved.
