1、The emergency is slopeed on the coal bed to sum up to pluckThe slanting coal bed is asked for a few minutes component that the slanting coal bed roof pressure uprightness hurried actes as to be used on stand either the coal post than postponeing ，But greatly along component that slopes the action ，T

2、he plank at coal bed peak base wholly slips along the trend probably ，The stand stability is bad ，As a result ading the complexity that extraction and sheltered work.Face pedestrian mines coal 、Transport stuff 、Coal drops 、Shelter 、The various workman sequence operation is collecting spece area hand

3、le and so on wholly comparatively more difficult ，Add the difficulty that the mechanize was mined coal .Oridinarily ，Hurry that the slanting coal bed has wholly udergo that the intense geology alters ，The geological structure is more complex ，The surrounding rock term is bader ；Mining coal beside ,

4、the face carryes forward velocity slowly ，Extraction leading is leted drop .As a result heads for length and asks for a few minutes than postponeing the slanting coal bed in the collecting area .The key that successful in the great dip coal bed ordinary set of use being living was mined coal is prop

5、erly resolving the good coal_winning machine 、Conveyer and stand antisliping problem .Guard against the main step of coal_winning machine glide slope station from possesing ：（1）Revising as the coal_winning machine anchor chain draws and gurrantees rated tractive effort ；（2）Being living the level fix

6、s the secure windlass antisliping ，Supplementarily draw the coal_winning machine ；（3）When the plank conveyer is fleeced in the slanting coal bed face of 450 left and right sides emergency in case being living ，The coal_winning machine is fixed the staff antisliping .The face conveyer step antislipin

7、g possess ：（1）Nose and tail all solder antisliping to fix the post pedestal admittedly ，Strikeing firmly antislips to fix admittedly the post ；（2）Being living the level installs the windlass antisliping ；（3）Have to sticing to moves when being living the transportation conveyer afterwards moves the o

8、rder down earlier ，Move the tail to fix upper part in face admittedly earlier ，Move the middle part trough again .The middle part trough ought to add the provisional post to fix admittedly by the burst .Guarding against the face stand glide slope station step is ：Adopt brining the base beam three po

9、sts parallel face shacks ，Liang Tou is docked ；Build the treadle antisliping between two rows of posts .With personnel staff old and young and the task doing being convenient for .The synthesis is mined coal , and necessary installation consists of twin cylinder coal_winning machines 、Support style

10、hydraulic pressure stand 、The emulsify fluid pump awaits .Composition and technique feature that the cylinder coal_winning machine is mined coal In 1976 manufactures experimently out MJW-80s mould coal_winning machine the March ，Such main master succeeds partly to be possess ：Electric motor ，Box dec

11、elerates ，Cylinder ，Low wheel stand ，The stand is in turn in the peak ，Suspending hoists the set ，Slips to sled and so on .The action that the stand is in turn in the peak is the cutting depth that causes the coal_winning machine maintain specified .The base wheel stand action is transferring to a l

12、ower level the direction in the interest of the coal_winning machine along the coal breastwork in face ，Moreover avert the coal_winning machine to topple over .Sliing the action which sledd is decreasing the obstruction that the coal_winning machine is living the plank slip at base ，Moreover cause c

13、ylinder tooth-tip together with coal bed base plank maintain the specified distance ，Avert the cylinder to cut the photographic plate in coal bed .Cylinder coal_winning machine fixing up of face .Elder 4050s rice of face ，Along slopes to fix up ，Along heads for carry forward .Practice proof ，Cut in

14、the process ，The face will take shape against heads for the slant face that the string succeeds 8085s degree angle of intersection certainly （Upper part is leaded ）。Draw outside the coal_winning machine adopts the means ，Drawing the windlass fixs in the recirculation air alley inner place .The natur

15、al law shelves are build up in the upper site in face ，Used to remove directing towards to the coal_winning machine .The guide of coal_winning machine joins with a hinge against the hydraulic pressure stand ，Pass in the way of the hoisting jack .Moving an order is transportation from bottom to top .

16、Extraction technology The main dependence self-esteem of coal_winning machine is feed ，Through gets off but goes up along the plank at base cuts the coal ，The coal on peak randomly sends out by self .The coal_winning machine competent till the face extremity is ，Cease to draw voluntarily .Afterwards ，By the coal_winning machine transfers to a lower level up the face gets off the extremity ，Dealing with to in turn the sky shelf newly removes f
