摘要
主要研究了窄煤柱工作面巷旁充填沿空留巷控制技术及应用.为了探讨煤柱的合理宽度,提出了最小煤柱宽度和最大煤柱宽度的计算方法,分析了充填沿空留巷支护方案的设计,以及如何应对窄煤柱工作面的安全问题.对于窄煤柱工作面,煤柱宽度不宜过大或过小,需要在安全和经济的基础上确定合理的范围,有效避免因煤柱宽度不合理而导致的安全事故,从而为窄煤柱工作面的安全生产提供一定的理论和实践参考.
Abstract
The control technology and application of roadside packing in gob-side entry retaining in narrow coal pillar working face were studied.In order to explore the reasonable width of coal pillars,the calculation methods for the minimum and maximum width of coal pillars were proposed,and the design of the support scheme for filling the goaf along the roadway was analyzed,as well as how to deal with the safety issues of narrow coal pillar working faces.For narrow coal pillar working faces,the width of the coal pillar should not be too large or too small.It is necessary to determine a reasonable range on the basis of safety and economy,effectively avoiding safety accidents caused by unreasonable coal pillar width,and providing a certain theoretical and practical reference for the safety production of narrow coal pillar working faces.
