案例：某年某月某日，某铁矿发生火灾事故，由于该矿和临矿互通，火灾共涉及5个铁矿，造成上百人被困井下。经多方抢救，遇难矿工人数仍达70人。随即成立了国务院事故调查组，调查组由国家安全生产监督管理总局、监察部、全国总工会、国土资源部、省人民政府联合组成，分为综合、技术、管理三个组。国务院事故调查组经初步调查，认定事故发生的直接原因是：该矿维修工在井筒内使用电焊，焊割下的高温金属残块及焊渣掉落在井壁用于充填护帮的荆笆上，造成长时间阴燃，最后引燃井筒周围的荆笆及木支护等可燃物，引发井下火灾。5家矿山越界开采，造成各矿井下巷道贯通，风流紊乱，火灾烟气蔓延，各矿均未按要求设置井下作业人员逃生的安全通道，直接导致了事故的升级和扩大。（说明：本题前5道题为单选题，后2道题为多选题。）
