宁东矿区厚层泥岩易垮落顶板控制技术

Roof Control Technology for Thick Mudstone that Easily Fall of Ningdong Mining Area

通过红石湾煤矿的煤岩层赋存性状,根据监测顺槽煤体内支承压力的分布规律及峰值,为以后区段煤柱的留设宽度提供依据,红石湾煤矿厚层泥岩顶板与宁东矿区大部分矿井顶板条件相似,具有代表性,为宁东矿区类似工程的预测预报提供参考。

According to the occurrence characters of coal rock of Hongshiwan mine,confirms the supporting scheme that control effectively,according to the distribution rule and peak of coal bearing pressure,providing the basis for the later section pillar width.Hongshiwan coal thick mudstone roof is similar to Ningdong mining area,which is very representative,and providing the basis for prediction of Ningdong mining area’s similar projects.
