By selecting and implementing the construction plan and technology of main shaft skip loading room at Zhaolou Mine,the paper introduced the adopted solution which fixed the problem during the construction of two-side arrangement skip loading room in the deep shaft under the big inflow condition.

Damping leakage layer has been adopted in terminal air distributing unit of airclean system An idea of damping leakage was obtained from another train of thought by which the filtrating air,uniformizing flow and caulking leakage of terinal unit has been decoupled It can damp leakage and change airflow easily,effectively and economically It is a new idea of air distributing uni
