6、小煤矿技术改造和机械化开采技术
实施国家关闭小煤矿，淘汰落后生产技术和生产设备，提高平均单井规模技术政策，改进小煤矿的采煤方法和开采工艺，提高采煤工作面单产和工效；提高小煤矿顶底板控制技术水平，最大限度地减少顶底板事故率。
7、煤炭地下气化技术
煤炭地下气化技术是将处于地下的煤炭进行有控制的燃烧，通过对煤的热化学作用而产生可燃气体的过程。煤炭地下气化技术属于一种特殊的采煤方法，它属国际首创。煤炭地下气化技术具有投资少、工期短、见效快、用人少、效率高、成本低、效益好等优点，尤其适合我国煤矿地质条件复杂、劣质煤比例高、“三下”压煤严重具体国情，具有广阔推广应用前景。应继续研究完善“长通道、大断面、两阶段”和“矿井式气化”两种典型煤炭地下气化工艺，进行较大规模地下气化试验研究，摸索实现“两个控制、三个稳定”的技术途径，并实现连续、稳定生产探索应用的途径。 参考文献

Coal Mining Technology
The Abstract：Nowadays science and technology the new situation of the economic development under, coal's mining a technical research has to be faced to domestic foreign two markets and faced to was constuct by the main battlefield, have a foothold in the coal mine technical of before follow, have a foothold the development is in the Chinese coal strategy necessity of technique storage, have a foothold strategic in the long-term development in the coal industry have to of the key offends a pass technically, have a foothold the industrial engineering is in the coal is actual the problem resolve, the point be engaged in the long-term research develop to store and technique, before following the industry science and technology follow, develop to have an independent intelligent property right of with the coal mine the technique and the kit material for predominant core technique, capture technique system a little bit high.
Keywords: Coal mining method,Control of surrounding rock, Roadway layout 1 Adopt the coal method and craft
Adopt the coal method and the progress of the craft with perfect is the topic that the always opencast academics develop.The development that adopts the coal craft will arouse the change that the coal mines each link, modern'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 combine 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 craft.Continue 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 theories.The 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 complications 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.

mine a technique.Produce by raising the work noodles list and produce concentration to change into core, with lift high-efficiency 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 and extend an application, raise to adopt the degree and the level of the coal mechanization.
(1) The development\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 definite direction water power etc. crest the plank dispatch a technique, make direct crest can with adopt with emit, exaltation crest the coal recovery rate, and the basic crest can press certain step to be apart from to fall, since be advantageous to a coal broken up, promise the safe production of the work noodles again. Hard and thick crest the coal control technique, the research development covers up a depth and pays to accept a hard and thick crest of small condition of pressure the dispatch of coal technique, including high pressure to note the water pressure technique and crest coal deep bore to prepare to blow up the processing technique, make a coal physique with adopt with emit, raise its recovery rate.
Crest the coal emit to put sex bad,piece degree the big release to adopt a set the equipments kit technique, develop since be advantageous to a coal broken up with crest plank control, and then be advantageous to the new liquid that puts a crest coal to press a support, the empress of the reasonable assurance the department transport function dint.
Under two hard conditions put a coal to mine fast push forward a technique, study suitable to release to adopt back to adopt a craft, excellent chemical engineering preface, shorten to put the coal time, exaltation the work noodles of the propulsion degree, carry out high produce efficiently.The 5-5.5 m breadth coal lane anchor man pole protects a technique, protecting the technical research development and application through the breadth coal lane anchor man pole, be advantageous to the adopts the kit equipments of the big power and

heavy type turn, contributing to continuously an application of adopt the coal machine, promote the work noodles of high produce efficiently.
(2) Tilt to one side long wall of thin coal seam to mine slowly.Main research development:The physical volume is small,power the thin coal seam of[with] big and high credibility adopt coal machine and plane coal machine;The liquid that develops to suit to plane the coal machine to adopt presses a support;The research develops the total kit technique of the thin coal seam work noodles with mine a technique efficiently.
(3) Tilt to one side thick coal seam slowly once to adopt whole thick adopt high and long wall to adopt greatly.Should strengthen the perfect support structure and strength further, add a strong support to defend to pour,antiskid,keep a beam from sew to open with four connect a pole to transform,prevent°from the serious damage jack measure research of[with] etc., suggest the credibility of the high support, contract the margin that it is high with medium thick coal seam(adopt a high 3 ms or so) to produce efficiently index sign.
(4) Various adopt high produce efficiently to adopt equipments guarantee system.Want to carry out to be high to produce efficiently, will raise to switch on a rate, to the \a rock\the luck equipments to carry on supervision.The point that will study from now on BE:Manipulate a support and change through the electricity liquid control valve set well\round a rock\system control, the further perfect liquid presses an information,the support ,crest plank appearance,pay to protect the quality information of from move to collect system;The examination that emulsifies the liquid pump station and liquid to press the system movement appearance examine a patient;Adopt the coal machine on-line and off-line monitor of[with]\whet scraps\monitor and temperature,the telecommunication number for combine together;The take type transports machine and pare off plank to transport overall appearance of machine supervision. 2 Deep mineral wells mine a technique
The key technique that the deep mineral well mine BE:The mineral that the coal seam mine presses a control,pound at ground to press the prevention and cure,gas and heat to harm to manage and the deep well breeze,the well lane decoration...etc.;Demand'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 variety of homework place work environment in deep well;The deep well tunnel(especially soft rock tunnel) digs quickly into with pay to protect the technique and material;Impact ground in deep well presses the prevention and cure
