ZZS6000/17/37A four pillars chock-shield is fully-mechanized support equipment that is designed for high output and efficiency mine.
ZZS6 0 0 0 / 17/ 37A型四柱支撑掩护式液压支架是专为“高产高效”矿井设计的综采支护设备。
When working face has mechanized support, air leakage quantity is small, velocity is low in goaf, and spontaneous combustion zone is more approach to working face.
有综采支架时，工作面向采空区的漏风量过小，致使采空区的速度很小，自燃带靠近工作面。
Permeability is a key factor to air leakage, its value and distribution influences greatly the distribution of air leakage. The mechanized support influence air leakage from working face to gob.
渗透率是解算采空区流场的关键参数，渗透率的变化对采空区的流场有很大的影响，而综采支架的存在，影响工作面向采空区的漏风。
