(4)Pay to protect the quality and crest plank dynamic state monitor the aspects of tally up slowly tilt to one side win thickly grow wall work noodles openning the exhibition to protect the quality and crest plank dynamic state monitor, should further at strong and tough crest the plank,broken up crest plank,nasty tilt to one side and put a coal work noodles to open the exhibition to protect the quality and crest plank dynamic state monitor, in the meantime should continuously perfect and existing monitor technique, develop intelligence to turn monitor system, improvement monitor appearance, make monitor appearance to keep a view,easy and convenient and small scaled turn a direction development. (5)Pound at ground the estimate and the prevention and cure for the mechanism that the calculator emulation research impact mineral presses to present occurrence。Finish to pound at sex mineral to press to present monitor system well further, develop to control from a distance measure and forecast a technique, the perfect impact mineral press prehensive prevention and cure measure of excellent turn choice expert system. (6)The research develop to pay to protect an equipments the hard coal seam,hard crest plank puts a coal liquid to press a support, the perfect liquid presses the support function with move a system quickly, develop to bear cannon to collapse,the light type turn single body fluid to press to pay pillar with the thick coal seam tunnel anchor man and the flexible anchor man pole. 6 Small coal mine technique reformation and mechanization mine a technique Carry out the nation closes small coal mine, eliminating to fall behind the production technique and producing an equipments, raising the technique policy of the single well scale equally, develop small scaled coal mine mechanization,the half mechanization to mine the technique and material, improve small coal mine to adopt the coal method with mine a craft, the list that raises to adopt the coal work noodles produces with the work effect。Raise the crest of the small coal mine scaleboard control technique level, reduce a scaleboard trouble rate with maximum limit. 7 Coal underground gasify a technique The coal underground39。s gasifying a technique is the coal that will be placed in an underground to carry on the bustion that has a control, passing to the hot chemical effect of the coal but producing can the process of the coal underground gasification technique belong to a kind of adopt the coal method specially, it belongs to nations to coal underground gasifies a technique to have an investment little,the work expect to be short and take effect quickly and use a person little,the efficiency is high,the cost is low,performance good etc. advantage, particularly in keeping with our country the coal mine geology condition plications,the inferior coal parison is high,three times press the coal severity to have the body state of the nation, have vast of 河 南 理 工 大 學(xué) 2021 屆 本 科 畢 業(yè) 論 文 (設(shè) 計(jì) ) 第 11 頁(yè) expansion application continue to study perfectlong passage,big cross section,two stages two kinds of typical model coal undergrounds to gasify a craft withthe mineral well type gasify, carry on a more largescale underground to gasify to experiment a research, grope for the technique path of the realizationtwo controls,3 stabilize, and carry out a consecution and stabilize to produce to investigate applied path.
