1. The comprehensive mining equipment does not match the belt conveyor. The comprehensive mining equipment is increased, while the belt conveyor is backward. (at present, the maximum production capacity of MG250 / 675-qwd shearer is 1400t / h, the maximum transportation capacity of see 830 / 315 transfer machine is 1500t / h, and the maximum transportation capacity of dsp1080-1000 belt conveyor is 800t / h) the belt is overloaded.

2.導致輸送帶偏離的因素很多，主要包括(1)輸送帶運行過程中的供水。煤巖層含水量大；前巷轉(zhuǎn)運機尾部低，抽排水和提升不及時，運行中供水和運行偏差連續(xù)。(2)輸送帶輸送機使用不同制造商生產(chǎn)的輸送帶。輸送帶的橫向和縱向伸長系數(shù)不同，輸送帶偏離。(3)輸送帶接頭不直，導致輸送帶兩側(cè)應力不均勻，接頭處出現(xiàn)弧形彎曲偏差。(4)拉動轉(zhuǎn)運機時，輸送帶機尾部移位，尾部不能及時調(diào)整，導致輸送帶跑偏。(5)皮帶超載，導致皮帶擦傷、打滑，落到張緊，導軌和滾筒，尾部，導致滾筒藏起貨物并向錯誤的一側(cè)跑去。

2. There are many factors leading to belt deviation, mainly including (1) water supply during belt operation. The water content of coal seam is large; the tail of the front Lane transfer machine is low, the drainage and lifting are not timely, and the water supply and operation deviation are continuous during operation. (2) Belt conveyors use belts from different manufacturers. The transverse and longitudinal elongation coefficients of conveyor belt are different, and the conveyor belt deviates. (3) The belt joint is not straight, resulting in uneven stress on both sides of the belt and arc bending deviation at the joint. (4) When pulling the transfer machine, the tail of the conveyor belt is displaced, and the tail cannot be adjusted in time, resulting in the deviation of the conveyor belt. (5) The belt is overloaded, causing the belt to scratch and slip, falling to the tension, guide rail and roller, tail, causing the roller to hide the goods and run to the wrong side.

3.阻燃輸送帶在重載下在三段托輥的槽角位置和頂槽處長時間彎曲。卸載后，輸送帶返回以恢復原狀。在操作過程中，輸送帶會長時間彎曲和折疊。輸送帶在三段惰輪的鏈接位置達到疲勞極限。表面粘合劑與帶芯分離，導致輸送帶縱向開口損壞。

3. Under heavy load, the flame-retardant conveyor belt bends at the groove angle position and the top groove for a long time. After unloading, the conveyor belt returns to its original condition. During operation, the conveyor belt bends and folds for a long time. The conveyor belt reaches the fatigue limit at the link position of the three-stage idler. The surface adhesive is separated from the belt core, causing damage to the belt longitudinal opening.

4.卸煤滾筒，尾滾筒，導軌滾筒， 張緊滾筒與整機不匹配，而滾筒直徑較小。輸送帶縱向轉(zhuǎn)動360度，輸送帶長時間通過各種滾筒，粘接面疲勞開裂，輸送帶芯部被進水侵蝕損壞。

4. The coal unloading drum, tail drum, guide rail drum and tension drum do not match the whole machine, while the drum diameter is small. When the conveyor belt rotates 360 degrees longitudinally and passes through various rollers for a long time, the bonding surface is fatigue cracked and the core of the conveyor belt is damaged by water erosion.

5.輸送帶滿載時，上面有雜物或大煤塊。當機器停止移動和卸載時，以及當機器重新啟動時，將導致重載提升、輸送帶過載、接頭斷裂和粘合面開裂，從而降低輸送帶的使用壽命。

5. When the conveyor belt is fully loaded, there are sundries or large coal blocks on it. When the machine stops moving and unloading, and when the machine is restarted, it will lead to heavy lifting, belt overload, joint fracture and adhesive surface cracking, thus reducing the service life of the conveyor belt.

6.轉(zhuǎn)移點有一個大的下降。原煤對輸送帶的沖擊導致輸送帶表面斑點損壞，輸送帶芯被腐蝕、老化和損壞。

6. There is a big drop in the transfer point. The impact of raw coal on the conveyor belt results in the surface spot damage of the conveyor belt, and the core of the conveyor belt is corroded, aged and damaged.

7.輸送帶(輸送機)檢修、操作和維護不到位；維修人員或磁帶司機責任心不強，巡回檢查不到位，磁帶隱患不能及時發(fā)現(xiàn)和處理，造成磁帶損壞。例如，輥不是很重要，但是如果它磨損了，會出現(xiàn)一個刀片，這可能會嚴重損壞輸送帶。

7. The maintenance, operation and maintenance of the conveyor belt (conveyor) are not in place; the maintenance personnel or tape driver have a weak sense of responsibility, the patrol inspection is not in place, and the hidden dangers of the tape cannot be found and handled in time, resulting in the damage of the tape. For example, the roller is not very important, but if it is worn, a blade will appear, which may seriously damage the conveyor belt.

8.儲存不當。輸送帶的儲存溫度要求在15-40之間；避免日曬雨淋。新買的輸送帶未能及時投入使用。由于該地區(qū)的寒冷和缺乏溫暖的儲存，它開始變硬，甚在使用前開裂。

8. Improper storage. The storage temperature of conveyor belt is required to be between 15-40; avoid sun and rain. The newly purchased conveyor belt was not put into use in time. Due to the cold and lack of warm storage in the area, it began to harden and even crack before use.

9.輸送帶本身的質(zhì)量問題。輸送帶加工過程中添加的阻燃劑降低了輸送帶本身的強度；編織芯線不符合標準，輸送帶僅使用一個月，個別點有縱向開口

9. Quality problems of conveyor belt itself. The flame retardant added in the processing of conveyor belt reduces the strength of the conveyor belt; the braided core wire does not meet the standard, and the conveyor belt is only used for one month, and there are longitudinal openings at some points
