摘要/Abstract

摘要： 为了保证神东矿区引进的旺格维利连采技术达到安全高效生产效果，并提高煤炭回采率，对大柳塔煤矿不同旺采工艺条件下的同区域不同区段回采进行了矿压规律监测研究。通过矿压监测数据对比分析可知，平巷护巷煤柱留设10m是能够保证隔离安全的；刀间煤柱留设0.5m的煤皮能够起到辅助连采机割煤装煤的效果，而不能起到支撑覆岩作用；支巷间2.0m厚度煤柱能够起到支撑顶板做用。试验区域回采区域面积突破公司规定，回采率提高12.3%，改革旺采工艺是成功的。

Abstract: In order to ensure Wongawilli mining technology imported by Shendong minning area to achieve safe and efficient production effects, and improve the coal recovery rate, mining pressure law monitoring was taken in different mining technology faces in same area in the Daliuta coal mine. Mine pressure monitoring data comparative analysis shows that, Lane roadway pillars leaving in 10m is to be able to ensure the safety of the isolation; Coal Pillar between sumpings is designed 0.5m to play a role of supporting continuous mining machine to cut coal and load coal and can not play the role of supporting the overlying strata; the 2.0m thickness coal pillar between branch lanes plays a supporting roof . The test mining area breakthroughs company provision and the recovery rate is increased of 12.3%, reform of Wongawilli mining process is successful.

Key words: overlying layers, shallow coal-seam, mining pressure law, Wongawilli mining technology, special structure
