【正文】 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 calculator technique actually, deep go into study various coal seam geology and mine a condition, such as nasty tilt to one side,adopt greatly high,adopt greatly to adopt a mineral mountain pressure to present regulation and round the rock breakage and equilibrium mechanism deeply, continuously perfect adopt a field to round a rock control technique. (2)Study a strong and tough crest plank the lath piece to descend the applied high technique low cost rock strata control technique with the broken up crest. Currently, because of applied high press to note a water,deep bore to prepare to blow up to handle a strong and tough crest plank and applied the chemistry reinforce the technique existence craft plications,cost high problem, as a result need the further research development a new technique,new craft,new material to resolve these problems. (3)Put a coal to mine the rock strata and supportround rock interaction 39。s surface waste toward to fall the method work noodles to adopt the system that the empty area fill。The deep mineral well is high to produce to mine a concerning kit technique efficiently。s offending what pass study BE:The deep well rounds the rock appearance with should the dint field and distribute the characteristic of the appearance。The examination that emulsifies the liquid pump station and liquid to press the system movement appearance examine a patient。s adopting the development direction of the coal craft is high to produce,efficiently,high safety with high and dependable, the basic path makes to adopt a high new technique of the coal technique and modern,to,bine,together,studying,to,destrongdint,efficiently,safety,credibility,enduring,the intelligence turn of adopt the coal equipments and production to supervise and control system, improve with perfect adopt a coal to develop multilayers at the time of developping a modern to adopt the coal craft,diver sification of adopt the coal craft, the establishment has Chinese special features to adopt coal craft our country is long the wall adopt the coal method to have already tend mature, put a coal to adopt coal of the application Be expanding continuously, applying the depth of the level and theories research with wide degree all Be raising continuously, nasty tilt to one side, unsteady,the geology structure plications etc. is difficult to adopt coal seam to adopt the coal method and the research of the craft contain very big space, the main direction improves the homework condition, raising a list to produce with mechanization level. Develop coal mine efficiently intensive turn a production technique,the construction produce height concentration,high credibility of high produce efficiently the mineral well to mine a by raising the work noodles list and produce concentration to change into core, with lift highefficiency with economic performance for target, study to develop under various condition of high performance,the high credibility adopt the coal material and craft, simple,efficiently,dependable production system with mine a decoration, produce a distance to supervise and control to manage etc. and science the kit is mutually of the set mine a technique, develop under various mineral well coal seam condition of adopt the coal mechanization, further improvement craft and material, raise applied level 河 南 理 工 大 學 2021 屆 本 科 畢 業(yè) 論 文 (設(shè) 計 ) 第 7 頁 and extend an application, raise to adopt the degree and the level of the coal mechanization. (1) The developmentshallow cover up deeply, hard crest the plank,hard coal seam is high to produce efficiently modern mine a set a technique, mainly solve a following technique hard nut to crack. Hard crest the plank control technique, the research covers up a depth,ground to press a small hard and thick crest the plank control technique, mainly pressing and tilting to one side deep bore to blow up through the rock strata
