摘要:
基于初始释放瓦斯膨胀能理论,根据突出模拟实验中发生突出时初始释放瓦斯膨胀能的临界值以及初始释放瓦斯膨胀能与瓦斯压力的关系,结合朗格缪尔方程,得出初始释放瓦斯膨胀能与煤层瓦斯含量的关系。该方法只需通过少量实验,就可以快速、准确得出煤样的初始释放瓦斯膨胀能,解决了通过瓦斯压力实验得出煤样初始释放瓦斯膨胀能测压周期长,特别是在地质破碎,裂隙发育的矿区很难准确测出瓦斯压力的难题。这一研究成果对石门揭煤和煤巷掘进中的突出预测具有重大意义。
Abstract:
Based on the expansion energy theory of initial gas diffusion, according to the critical value of expansion energy of initial gas diffusion appeared in the outburst simulation experiment and the relationship of expansion energy of initial gas diffusion and coal seam gas contention, through the Langmuir equation, the relationship of expansion energy of initial gas diffusion and coal seam gas contention was obtained. Only by several experiments, we can rapidly and accurately obtain the expansion energy of initial gas diffusion, the difficult problem of long period pressure measurement through the expansion energy of initial gas diffusion, especially in the crushed geological area and the crack development area was solved. This result has great significant to the outburst forecast of uncovering coal in crosscut and coal road tunneling.
