赵庄二号井1303工作面过空巷技术

Passing Through Empty Roadway Technologies of 1303 Working Face in Zhaozhuang No. 2 Mine

为了保证赵庄二号井1303综放工作面顺利通过空巷,在对空巷的支护情况,顶底板岩性、层位等进行分析的基础上,提出了前期加固充填空巷、调整工作面成伪斜状态的过空巷工艺和措施。应用表明,该方法确保了工作面顺利通过空巷,成功延长了工作面的服务年限。

To ensure the fullymechanized top coal caving face passing through the empty roadway successfully in Zhaozhuang No. 2 Mine, based on the analysis on supporting conditions,lithology of roof and floor,layers of empty roadway, specific techniques and meas ures were proposed to reinforce and fill the empty roadway in the earlier stage and to adjust the working face into oblique roadway. The application effects of this technology indicates that, this method can guarantee the success of working face passing through the empty roadway, and extend the service life of working face.
