针对大面积火灾气体不断流向工作面的问题,基于能位控制法,提出在火区与工作面之间布置CO隔离措施巷,利用措施巷卸压高能位火区、封堵漏风通道和工作面调压通风等技术,实现了火区、措施巷与工作面之间的能位平衡,高效解决了韩咀矿1202首采工作面CO超限的治理难题。
Aiming at the problem that a large area of fire gas flows to the work surface continuously, based on the energy control method, it is proposed that the CO isolation measures lane be arranged between the fire area and the work surface, the measures of alleviating the high-energy fire area, blocking the air leakage passage and the working surface Pressure ventilation and other technologies to achieve the fire area, measure the energy balance between the lane and face, effectively solve the South Korean coal mine 1202 first mining face CO overrun the governance problems.
