支承压力影响下防火密闭构筑物构建

Abutment pressure under the influence of fire prevention sealing structure building

为了合理确定在支承压力影响下防火密闭墙的位置及结构,文中结合工作面支承压力分布规律,参考FLAC 3D数值模拟结果和《矿井密闭防灭火技术规范》中的相关要求,最终确定联络巷防火密闭构建在距辅运顺槽副帮4~7m;确定了工作面平巷联络巷防火密闭采用"1.0m混凝土墙+1.0m罗克休充填层+1.0m混凝土墙"的结构形式,提出了密闭构筑物使用过程中的管理要求。

in order to reasonably determine the abutment pressure under the influence of fire location and structure of the seal, in this paper,in combination with working face abutment pressure distribution law, refer to the FLAC 3 d numerical simulation results and the technical specification for the mine closed fire extinguishing the relevant requirements, the final connection fire airtight build from the auxiliary transport gateway deputy for 4 - 7 m;Determine the heading face connection fire sealing adopts ／ ＂1.0 m ＋ 1.0 m rocsil foam concrete wall pack ＋ 1.0 m concrete wall／＂ the structure of the form, put forward the airtight structure management requirements in the process of use.
