As it's known to all, taking full advantage of useful information in university information management systems can improve the quality and efficiency of university management. With the aim at the characteristic of the information management system, this paper proposes practical applications of the Data Mining in university information management by analyzing the process, main workload and main technical methods of data mining. And finally, we provide some guidance information and reference information for the university management staffs to help them accomplish the university management quickly and efficiently.

Tunnel roof separation monitoring is an important research content of tunnel supporting technology, it is of great significance to guarantee the safety of mine production. The traditional detection methods of roof separation have disadvantages of low precision, poor reliability, high cost, and the comprehensive analysis of measurement results is difficult. In the paper, a roof separation monitoring device based on STC12C5A is proposed. It has the core of STC12C5A single-chip microcomputer, and realizes the accurate measurement of displacement by using the fine drag-rope displacement sensor, and realizes the data communication and sharing by using bus interface. The device can achieve real-time, reliable monitoring of roof separation condition and also can make pre-caution to the possible production accident.

Coal Mine Safety Monitoring System is an important material guarantee for Coal Mine Safety Production. At present,most China's coal mines have established safety monitoring system, but in the use of safety monitoring system we've found many problems. In order to solve these problems ,our paper put forward some practical solutions. [1].

As the application of the information network technology continuously extended, library management service platform is experiencing a shift to the information service system. In the library information management field, researchers are seeking a library identification system which is more convenient and comprehensive. Under the circumstance of the information technology conditions, Radio Frequency Identification (RFID) technology completes the automatic identification of the electronic identification tags--the two-dimensional code. The RFID technology is a contactless scanning recognition technology. And the core technology of RFID can be described as follows: using two-dimensional code as the filter identification tool according to backup data of the book management.
