摘要
将工作面划分为若干单元,测定每个单元进出风流热力状态,可得出工作面风流在每个单元的各种得热量、得湿量,分析所有单元的各种得热量、得湿量,可得出工作面的热湿源分布状态。通过对济宁二号煤矿3305工作面的单元法测定,发现该面主要热湿源是采空区漏风和煤壁,与采空区漏风相比,煤壁是更主要的热湿源。减少济宁二号煤矿3305工作面的煤壁散热、散湿量是改善工作面热湿环境关键。
Dividing the face into several elements, measuring the heat state of in and out air flow in every unit, all kinds of hest and wet gained from every element can be achieved. By analyzing all the elements, a distributing state of heat and wet sources in the face will be illustrated. Using this method in the face 3305 of Jining No.2 coal mine, it is found that the main heat and wet sources come from coal wall and gob breathing, comparatively the coal wall takes the major part. In the light of this, reducing heat and wet dissipating from the wall in the face 3305 is the key part for improving the face environment.
