提出了用强化泡沫充填上隅角,防止瓦斯积聚方法。在实验中研制了一种用于提高泡沫性能的强化剂,通过对3种发泡剂及其复配以及和强化剂的协同效果对泡沫的性能进行了研究,找出了最优的发泡剂。同时研究了发泡剂质量分数以及强化剂质量分数对制备高性能的上隅角充填泡沫的影响。结果表明,当发泡剂的质量分数为5%,强化剂质量分数为1%时,制得的充填泡沫性能最好。并在实验室研究的基础上,在淮北桃源煤矿成功应用,效果良好。
A method of filling the upper corner with reinforced foam to prevent gas accumulation was proposed. In the experiment, we developed a kind of enhancer to improve the performance of foam, studied the performance of the foam through the synergistic effect of the three kinds of foaming agent and its compound and the strengthening agent, and found the optimal foaming Agent. At the same time, the influence of the foaming agent mass fraction and the strengthening agent mass fraction on the preparation of high-performance upper corner filled foam was studied. The results show that when the mass fraction of the foaming agent is 5% and the mass fraction of the reinforcing agent is 1%, the prepared foam is the best. On the basis of laboratory research, it has been successfully applied in Taoyuan coal mine in Huaibei and has good effect.
