Taking ventilation shaft lining of Wujia Mao mine in Shanxi province as a research object, the design of the hanging plate's beams by the layout of constructing equipments was done. Using the ANSYS software to establish 3D model of the hanging plate, after conducting constraint and load, solving in ANSYS solver, and using Mises yield criterion, the equivalent stress distribution was obtained. Its force nephogram and displacement changes showed that the stress of the plate, and the deflection of the hanging plate. Based on displacement change of hanging point in case of grab loader working and no-load, the results show that hanging scaffold would vibrate with 0.25 m vibration amplitude.

The direct cause of gathering pipe network failure was the failure of the pipeline and accessories equipments according to a lot of field investigation .The fault tree was established as the top event of gathering pipeline failure on the basis of the comprehensive analysis of gathering pipeline network failure factors. Considering about the 44 basic events, the descending method was used to analyze the gathering pipeline network failure fault tree, and obtained all 52 minimum cut sets in the system. And the quantitative analysis of the fault tree was carried on. The qualitative analysis was carried on the gathering pipe network and the weakest link was found out in gathering pipe network, which could maintenance the old pipeline network and provide theoretical guidance for the design of the new pipeline network.

n order to more accurately determine the crude oil batching transportation temperature fluctuation, the soil temperature field around pipeline insulation surface drift was studied. For variation characteristics of soil temperature field around underground pipeline in the process of batching transportation of cold and hot crude oil, the non steady heat transfer model was established, and soil temperature field in different period of batching cycles and moments was numerically simulated and analyzed by using CFD software in the process of crude oil batching transportation. The results show that the drift on the thermal insulation surface of soil temperature field has certain regularity, and adiabatic surface with crude oil batching transportation time shows periodic drift, drift period and period of batching cycles of cold and hot oil transportation were the same; drift cycle of thermal insulation surface of soil temperature field and the scope are related to cold and hot cycle on the batch transportation of oil.
