摘要
通过对土城子井复采区域的现存状况的研究,当巷道掘进困难时,采用了打撞楔的方法通过,解决了在复杂条件下巷道掘进中支护问题,及在回采过程中的一些管理问题,为矿井安全考虑,提出了防治结合的综合防灭火技术,通过各种技术的综合应用,使复杂条件下旧区复采成为现实。
Through research of Tuchengzi repeated mining area at present, when faced difficulty of excavating,we adopted the method of strike wedge, which solved the question of support in complex conditions tunneling, and some manage issues in the process of mining. For mine safety, we puts forward the control of combination technology of fire prevention, and make old area repeated mining come to re- ality through all sorts of comprehensive application.
