综采工作面过F1正交逆断层安全开采实践

Safe Mining Practice of Fully Mechanized Mining Face Crossing F1 Orthogonal Reverse Fault

山东万祥矿业公司6198综采工作面过落差3.4~4.5 m的正交逆断层过程中,通过采取超前注浆加固、顶板铺设金属菱形网、锚杆加固、测量控制两盘煤层高差起底等特殊施工技术措施,安全快速推采过断层,避免了推采速度慢引发自然发火等。

In the process of the 6198 fully mechanized mining face crossing the orthogonal reverse fault with a drop of 3.4-4.5 m in Shandong Wanxiang Mining Industry Company,by adopting special construction technical measures such as advanced grouting reinforcement,roof laying metal diamond net,bolt reinforcement,surveying and controlling the height difference between the two coal seams and so on.It is safe and fast to push through the fault to avoid spontaneous combustion caused by slow mining speed.
