摘要
为了解决特厚煤层综放工作面临空巷超前支护段压力显现强烈的问题,研发和改进了一种新型的临空巷超前支护门式支架,提高了超前支护的强度,降低了工作人员劳动强度,方便了物料进出,取得了较好的安全技术效果。
In order to solve the problem of strong pressure appearing in the advanced support section of goaf in fully mechanized top coal caving face of extra thick coal seam,a new type of portal support for advanced support of goaf is developed and improved,which improves the strength of advanced support,reduces the labor intensity of staff,facilitates the material in and out,and achieves better safety technical effect.
