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。

youdao

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。

youdao

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。
