The paper gives detailed narration to the realization to the system for managing the info of the equipments in the medium and small scale coal enterprise, function of each module of the system and the development circumstances of the system. 【Descriptors】 C / S Coal mine Equipment Tunnelers & Excavators Calculation and Analysis to the Main Technical Parameters of the Tunnel Boring Machine..........................................................................CUI GuoHua et al.(11-14) The paper studies the key technical parameters of the TBM such as the external load, thrust force, torque of the cutterhead and power etc., and makes analysis and discus- sion respectively by the theoretical formula and the experience approach. Combining the soil pressure balance TBM selected in certain tunnel construction, the paper makes check calculation to the key parameters. 【Descriptors】 TBM Technical parameter Thrust force Torque Power Optimization Design and Study to the Virtual Prototype of the TBM Cutterhead...... ......................................................................................WANG Qiang et al.(14-16) The paper establishes the three-dimension solid models for the cutterhead and tool of TBM in different geological conditions by Pro / E software, and the three-dimension model is introduced into the ANSYS software to make the finite element stress analysis, calculation to the stress and strain, timely modification to the structural design, virtual assembly and interference check between the cutterhead and TBM, which lead to the realization of the optimization design to the virtual prototype of TBM cutterhead. 【Descriptors】 TBM cutterhead Finite element analysis Virtual assembly New Kind of Theory for in Situ Testing the Shear Strength of Marine Sediment.... .....................................................................................WU HongYun et al.(16-17) The paper introduces a new kind of theory for in situ testing the shear strength of marine sediment, that is to say, the measurement to the shear strength of marine sediment is transferred to the measurement to the alternation of the pressure of oil in the sealed oil cylinder, then the data is output by the sensor and processed, thus the original value of the shear strength of the marine sediment is concluded. It also analyses the theoretical feasibility of the testing theory. 【Descriptors】 In situ test Volume flexibility modulus Dynamic performance Shear strength Influence of the Distribution of the Normal Pressure Acting on the Pedrail of the Mining Vehicle in Deep Ocean to the Driving Force...DENG YueHong et al.(18-19) The paper initiates with the generating mechanism of the force driving the pedrail, analyses the influence of five kinds of distribution style of the normal pressure to the performance of the driving force of the mining vehicle in deep ocean, concludes the relationship chart of influence of the distribution of the normal pressure acting on the pedrail to the driving force—sliding ratio properties, which offers the theoretical reference for the whole design to the pedrail helix roller mining vehicle in deep ocean. 【Descriptors】 Normal pressure Driving force Sliding properties Loaders & Haulers Development Course of the Road Roller............................ZHAO YuDong(40-42) The paper discusses the road roller about its development course, technical innovation, structural characteristic and the new development on atomization. 【Descriptors】 Road roller Structure Innovation Development Design to the Gas Exhaust of Deutz Diesel in the Underground Trackless Mining Tramcar..........................................................................GAO MengXiong(43-45) The paper introduces the design to the gas exhaust of Deutz diesel in the underground trackless mining tramcar about its significance, design principle and content. 【Descriptors】 Diesel Design to the gas exhaust Purifier for the exhaust gas Muffler Study to the Match between the Hydraulic Torque Converter and the Engine of the Tramcar..............................................................ZHANG GuoFen et al.(46-49) The paper makes the analytical study to the principle and estimation index of the。
