Based on the actual conditions of the 5342 fully mechanized caving face of Wulan Coal Mine, the 3-D distribution of gas in the face is tested by measuring points arrangement in the stereo grid. The isograms of gas distribution of the face are drawn. Gas concentration nadir distribution curve along the working face incline direction is drawn by method of seeking function minimum points. The method of calculating gas emission components ratio of the face by means of the curve is brought forward.

Currently in a surface warship of the our country everyplace all provided with the sail coal gas body to report to the police the instrument on the boat, gas density that sensor adopt to convey gas density value traditional 4-20mA mode of analog signal, have to each measure passway allocate one is it is it report to the police to measure to have and density value show measuring board of function, as the density of gas measures the passway board of the different quantities of different outfit of the figure of the passway, but there is many figure of the large-scale naval vessel passway, so the volume of warning system will become very huge , unfavorable to attenbants to use, and traditional 4-20mA electric current ring transmits the signal, unfavorable to transmitting at a long distance, easy to bring and interfere.

核心提示：摘要目前在我国各地型水面舰船上都配备了航煤气体报警仪，气体浓度传感器采用的是传统的4-20mA模拟信号的模式传送气体浓度值，只好每个检测通道配备一块具有检测报警及浓度值显示功能的检测板，随着气体浓度检测通道数目的不同配备不同数量的通道板，但大型舰船通道的数目比较多，因此报警系统体积会变得十分庞大，不利于操作人员使用，而且传统的4-20mA电流环传输信号，不利于长距离传输，容易带来干扰。为了巡检的需要，需要将其改造成现场智能仪表，通过将传感器检测结果
