容大煤业6号煤层巷道支护设计及参数计算

Design of Roadway Support and Calculation of Parameters for No.6 Coal Seam in Rongda Coal Industry

根据围岩性质、巷道用途及服务年限、巷道受采动影响程度等因素确定容大煤业6号煤层巷道的支护形式。利用动态设计法,结合矿方现有的支护技术水平,提出巷道支护设计方案。方案在井下实施后,开展矿压监测,总结巷道矿压显现规律,根据煤矿后期采掘部署,进一步优化巷道支护方案。

The support form of No.6 coal seam roadway in Rongda Coal Industry was determined according to the nature of surrounding rock,the use and service life of the roadway,and the degree of the roadway being affected by mining movement.Using the dynamic design method and combining with the existing support technology level of the mine,the roadway support design scheme was proposed.After the program was implemented underground,mine pressure monitoring was carried out to summarize the law of mine pressure manifestation in the roadway,and the roadway support program was further optimized according to the later mining deployment of the coal mine.
