根据新集一矿C13煤131303综放工作面实际情况，通过实测和模拟实验，对C13煤层综采放顶煤工作面采空区自燃“三带”分布进行了测定，结合采空区煤炭自燃理论，得出“三带”分布规律和各带的数值范围，计算了工作面推进度，同时确定了工作面防灭火技术参数，为防灭火管理提供了科学依据。
根據新集一礦C13煤131303綜放工作麵實際情況，通過實測和模擬實驗，對C13煤層綜採放頂煤工作麵採空區自燃“三帶”分佈進行瞭測定，結閤採空區煤炭自燃理論，得齣“三帶”分佈規律和各帶的數值範圍，計算瞭工作麵推進度，同時確定瞭工作麵防滅火技術參數，為防滅火管理提供瞭科學依據。

According to the actual situation of C13 coal in131303 fully mechanized caving face, through the observation and simulation experiment, the C13 coal seam fully mechanized top coal caving working face goaf spontaneous combustion "three zones" distribution were measured, combined with the theory of spontaneous combustion of coal in goaf, the"three zones"distribution and the numerical range, calculated the mining speed , while determining the technical parameters of working face of ifre prevention, and provided the scientiifc basis for the ifre prevention management.
