摘要
为了加强无煤柱回采综放工作面沿空留巷顶板管理,提高巷道支护挡矸效果,减少采空区瓦斯涌出。山西高河能源有限公司通过技术研究,对E1315沿空留巷采取柔模浇筑技术进行巷道围岩控制,实际应用效果表明,采用该技术后提高了顶板稳定性及挡矸效果,降低了瓦斯涌出量,取得了显著成效。
In order to strengthen the roof management of gob-side entry retaining in fully mechanized top coal caving face without coal pillars, improve the supporting effect of roadway to prevent gangue and reduce the gas emission from the goaf, Shanxi Gaohe Energy Co., Ltd. adopts flexible die technology to control the surrounding rock of E1315 gob-side entry through technical research. The practical application results show that this technology improves the roof stability, contributes to preventing gangue and reduces the amount of gas emission. Its remarkable results have been achieved.
