许疃煤矿采空区“三带”范围确定及应用
etermination of “Three-Zone”in goaf in XuTuan Coal Mine and its application
根据许疃煤矿3235工作面实际情况，沿采空区两顺槽布置4个测点，对采空区温度及气体成分进行测定，确定3235工作面采空区自燃“三带”的范围, 根据测定结果合理确定了工作面防灭火技术的工艺参数，通过“三带”的范围计算了工作面极限推进速度。为防治井下煤炭自燃提供科学依据，保证了工作面的安全回采。
ccording to the actual situation of NO.3235 working face in XuTuan coal mine ,four testing points were located along two tunnel in goaf to measure temperature and gas component so as to determine the three-zone of spontaneous combustion in goaf.The specified parameters of fire-prevention technology was established , the limit advance speed of working face was calculated . The achievements provide the scientific basis for preventing the mine spontaneous combustion.
