杨村煤矿315工作面过老巷分段性充填技术应用

摘要

In order to recover more coal resources, the Yangcun coal mine 315 fully mechanized caving face is designed for passing the goaf recovery protection pillar face. Through research, segmented filling technology passing the old roadway is used in field practice. According to the arrangement of old roadway and face, the actual status of face and face strata behavior regularity, it conducted segmentation of roof and floor filling treatment to the old roadway in mining influence sphere, which effectively solved the high cost, long time and big mining influence and other issues, and has achieved notable results.%　　为了多回收煤炭资源，杨村煤矿315综放工作面设计为过老巷回收保护煤柱工作面。通过研究，确定了过老巷分段性充填技术并应用于现场实践，根据老巷与工作面的布置关系、工作面的回采实际现状以及工作面矿压显现规律，超前对回采影响范围的老巷进行分段性顶板、底板充填处理，有效解决了传统充填法充填成本高、耗时长、对回采影响大等问题，成效明显。
