On-line test system and method by establishing mainboard managerial control using local loop

A test system which utilizes local loop to set up main-board management control connection comprises more than one host terminals that are provided with at least one network card, and at least one main board management controller that is provided with at least one network card. After a test connection is set up between the host terminal and the remote user, the host terminal sets up loop test connection with the main board management controller by the means of virtual address to send test command to the main board management controller for testing and test results are reported. The invention sets up loop test connection by virtual address to carry out remote test that is similar to internal loop test, thereby avoiding test results being affected by the network environment setting and ensuring batch test to save testing time.

Method and system for continuously pumping gas in coal uncovering process of vertical shaft

The invention provides a method and system for continuously pumping gas in the coal uncovering process of a vertical shaft. The method comprises the following steps of: constructing a concealed gas pumping pipeline groove on a section which is a preset distance away from a shaft barrel of the vertical shaft by blasting; pre-burying a gas pumping pipeline in the concealed gas pumping pipeline groove; constructing a plurality of pumping drill holes on an uncovered coal seam outside a wild path at the bottom of the shaft barrel of the vertical shaft; and pumping gas from the uncovered coal seam by using a gas pumping hose which is connected with the gas pumping pipeline and is arranged in the plurality of pumping drill holes. By adopting the method and system for continuously pumping gas in the coal uncovering process of the vertical shaft, provided by the embodiment of the invention, the technical defect of unavailable continuous pumping of coal seam gas due to frequent damage of blasting ...

Comprehensive coal seam structure forecasting system based on earthquake-radar

The invention relates to the field of geophysical exploration, in particular to a coal seam structure comprehensive forecasting system based on earthquake-radar. Comprising an earthquake database, a mine radar data acquisition system and a data management interpretation center. The seismic database is mine three-dimensional seismic interpretation data and is used for forming a preliminary interpretation result for the overall structure of a coal seam; the mine radar data acquisition system is used for detecting coal seam structure information by using a mine radar and performing comparison verification on the coal seam structure information and a three-dimensional seismic interpretation result; the data management interpretation center is used for combining the seismic exploration data and the mine radar data for mutual comparison and fusion analysis; the forecasting system is simple in structure, intelligent and efficient, integrates the advantages of a seismic exploration method and a ...

Method for uncovering coal in vertical shaft

The invention discloses a method for uncovering coal in a vertical shaft, which comprises the following steps of: acquiring engineering information of a coal bed to be uncovered in the vertical shaft, judging whether the coal bed to be uncovered is an outburst coal bed or not according to the engineering information, and if so, performing outburst prevention treatment on the coal bed to be uncovered; and uncovering the coal bed to be uncovered after the outburst prevention treatment. Compared with the technical scheme that all coal beds to be uncovered are subjected to the outburst prevention treatment and then the coal beds to be uncovered are uncovered in the prior art, the technical scheme of the invention is that: whether the coal bed to be uncovered is the outburst coal bed or not is judged first, if the coal bed to be uncovered is the outburst coal bed, the outburst coal bed is subjected to the outburst prevention treatment, and the coal bed to be uncovered after the outburst prevention ...
