【正文】 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 2021 屆 本 科 畢 業(yè) 論 文 (設 計 ) 第 11 頁 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. 。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。s putting a coal to mine mechanics model and rounding a rock should the dint,crest mechanism with broken up coal,the supportcrest coaldirect crestbasic crest interaction relation。Study the stone a direct processing under the well and Be the technique that the 充 fills material, since is reduce polluting emollient measure, and then simplify production system, be advantageous to high produce to concentrate to turn to mine efficiently, should step up a research. 5 Adopt a field to round a rock control technique (1)further perfect adopt a field to round rock control science is reasonable and excellent to turn efficiently of the rock strata control technique to promise a safety of mine the activity,efficiently,low cost is target, thorough summary our country the mineral mountain pressure of several decades research result, with theories analysis(solution the method),modern mathematics mechanics(statistics analysis estimate,the number method) with measure a method to bine together the usage forerunner39。Research and apply various to fill technique and bination to fill a technique, the village house reinforces the reformation reconstruction technique, being suitable for the village protection to mine a technique。s surface,building,the groundwater resources protection to need of reasonable of mine system with excellent turn parameter, develop to sink to decline the control theories and the key technique, include to use the earth39。The deep mineral well mines heat to harm to manage the technique and material. 3 Three timess adopt a coal technique The exaltation number imitates the calculation and alike material to imitate etc., the thorough research mines to exercise to sink to sink regulation and eart
