[Abstract]:The 1103 face of Pingshuo No.2 Mine is the first mining face of 11 coal, and the 1103 face needs to be mined in the close distance 9 coal goaf and under the remaining coal pillar. Fully-mechanized mining technology with large mining height under close goaf is the first time to be applied in Pingshuo mining area. The summary of the law of mine pressure on the first mining face has important guiding significance for the subsequent mining of other working faces. At the same time, because of the special mining conditions and complex rules of mine pressure, a large number of field monitoring data need to be obtained. Manual analysis is not only a heavy workload, but also the accuracy and efficiency will be very low. It is necessary to develop the analytical software to realize the automatic analysis of the pressure parameters and the operating parameters of the support. Aiming at the 1103 mining face, this paper studies the law of mine pressure in this working face by means of field investigation, physical and mechanical parameters measurement of coal and rock in laboratory, on-site monitoring of mine pressure and theoretical analysis. Through field investigation and sampling, the geological data of Jinggong No.2 Mine and 11 coal and roof rock samples were obtained. W4-130 universal testing machine, YES-200 digital display uniaxial compression tester and YJ-5 resistance strain gauge were used in the school laboratory. The physical and mechanical indexes of coal and rock specimens were measured by uniaxial compressive strength test and splitting tensile test. Through the field monitoring, the working resistance of the support, the roof and bottom plate moving close and the roof falling from the mining face are obtained. By using VB language to develop the analysis software of rock pressure law, a series of pressure parameters and support operation parameters, such as the pressure step distance and pressure intensity of 1103 mining face, are calculated by the monitoring data obtained. Finally, the rock pressure law of 1103 mining face is summarized by analyzing the data processing results. In this paper, the rock pressure law of 1103 face is summarized successfully, and the applicability of the support is evaluated and summarized at the same time. The research results are of great significance to the mine, which not only provides an important basis for the safety production of the subsequent working face, but also provides a reference for the selection of the follow-up support. At the same time, there are few researches on the analysis of mine pressure law by VB language, which can be used as a reference for other mine pressure law research methods.
