针对当前工作面传统拆除工艺,综合矿井提升能力、井下巷道条件、人工及材料成本等诸多方面因素,根据当前实际制定了一套大采高工作面少坑木支护拆除新工艺施工方法,确定了在采用大采高工作面少坑木支护拆除新工艺时顶板管理、通风设计等具体的工作方案。同时还针对少坑木支护拆除新工艺在施工过程中可能存在的安全隐患,制定了具有科学性、针对性、可操作性的安全技术措施,有效地保证了施工安全顺利进行。
Aiming at the current dismantling process of traditional working face, comprehensive mine lifting ability, underground tunnel conditions, labor and material costs and many other factors, according to the current actual development of a large mining face less pit support timber removal of new construction methods, to determine In the use of a large mining face less support and removal of new pit support technology, roof management, ventilation design and other specific work programs. At the same time, aiming at the potential safety hazard in the process of construction of the new technology of dismantling the support of a small pit, a scientific, pertinent and operable safety technical measure is formulated to effectively ensure the smooth construction safety.
