Abstract
The utility model discloses a measurer of conspicuous parameters of coal and gas with simple structure and all-plastic, which can provides a basis to the degree of safety of the gas drainage from virgin coal seam and outburst prevention. Simultaneously, the utility model can detect the useful effect range of other coal and gas outburst prevention measures, such as the hydraulic flushing in hole, the drill hole methane drainage, the hydraulic washing, the pressure relief chamber (slot), etc. The device transfuses the synthetic index of the gas influenced by the coal bed gas pressure, the crustal stress and the mechanical property of the coal and judges the degree of safety of the coal and gas outburst after adopting the outburst prevention measures. The measuring method is convenient, accurate and reliable, and the long distance telemetry can be also achieved.
Description
The utility model relates to a kind of after taking to prevent coal and the outstanding measure of gas, measure the coal and the outstanding parametric measurement device of gas of its safe coefficient, this device can be to pre-gas pumping, prevent that the outstanding safe coefficient of coal and gas from carrying out continuous detecting and data are provided, simultaneously, also can detect hydraulic flushing in hole, boring firedamp drainage, sluicing, release cave (groove) wait other to prevent the effective range of coal and the outstanding measure of gas.
In this technical field, since finding and adopting pre-gas pumping to prevent method for protrusion, still do not had both at home and abroad and taken out the pick-up unit that protrusion-dispelling reaches safe coefficient in advance.At present, single factor determinator of common usefulness, as: coal-bed gas pressure, coal-bed gas bulk storage index (Δ P), ultrasound wave geodetic stress, MD-1 type desorption of mash gas instrument etc. all can not reflect terrestrial stress, coal-bed gas pressure comprehensively, the combined action result of factors such as the mechanical property of coal, can only reflect one of them or two exercising result, the forecast coal is not high with the accuracy of the safe coefficient that gas is given prominence to, and directly influences the safety of Coal Production.
In order to solve above-mentioned the deficiencies in the prior art, the utility model proposes a kind of coal and gas simple in structure, all-plastic and give prominence to the parametric measurement device, the measured data of this analyzer are outstanding parameter--the concentrated expression indexs of all parameters of mechanical property of coal-bed gas pressure, terrestrial stress, coal of coal and gas, with this index, judge the safe coefficient of coal and gas outburst danger, assay method is easy, and is reliable comprehensively.
The outstanding parametric measurement device of this coal and gas comprises center-pole A; center-pole B; sensor; drive link; inner sleeve and outer tube; one end of inner sleeve is fixed on the center-pole A; the other end can slide on center-pole B; guarantee the axially loaded direction of foil gauge in the sensor; guarantee that center-pole is not collapsed and fall the broken coal extruding and block; outer tube is manufactured by bibulous paper roll, is fixed on the jag of two center-poles, and the paper roll outer tube is as the protecting sheathing of analyzer when transportation is installed; fixing two center-poles did not simultaneously relatively move before analyzer enters duty; drive link one end is fixed on the center-pole B, and the other end is bolted on the center-pole A with regulating, and regulates bolt by degree of tightness and makes sensor be in equilibrium state before work.
As shown in the figure:
Fig. 1 is a structural drawing of the present utility model
Embodiment below in conjunction with accompanying drawing provides does further explanation to the utility model.The outstanding parametric measurement device of this coal and gas comprises anchoring body (1); center-pole 2A; center-pole 2B; regulate bolt (3); binding post (4); lead-in wire groove (5); adjustment hole (6); inner sleeve (7); outer tube (8); sensor (9); drive link (10); end cap (11) and guide head (12); anchoring body (1) is a compressed wood; anchoring agent or anchoring cartridge etc.; the two ends center-pole 2A and the 2B that are connected with anchoring body; be fixed on 2 points in the gaging hole by anchoring body (1); drive link (10) one ends are fixed on the center-pole 2B; the other end is fixed on the center-pole 2A with regulating bolt (3); by adjustment hole (6); degree of tightness is regulated bolt (3); make sensor (9) carry out being in equilibrium state before the duty at analyzer; inner sleeve (7) one ends are fixed on the center-pole 2A; the other end can slide on center-pole 2B; guarantee the axially loaded direction of the foil gauge in the sensor (9); and guarantee that center-pole 2A and 2B are not collapsed and fall the extruding and the obstruction of broken coal, outer tube (8) is made by the big paper roll of hydroscopicity, is fixed on the jag of center-pole 2A and 2B; the paper substrate outer tube is as the protection overcoat of analyzer when transportation is installed; fix two center-pole 2A and 2B simultaneously and do not relatively move before analyzer work, after analyzer was put into gaging hole, the moisture absorption of paper roll overcoat was softening; remove the relative fixed of two center-pole 2A and 2B; enter duty, center-pole 2A and 2B move, the sensing element generation deformation of sensor (9); send out signal by lead, obtain the overall target of the outstanding safe coefficient of coal and gas.
Claims (3)
1, a kind of to taking to prevent the safe coefficient of coal and the outstanding measure of gas, the coal and the outstanding parametric measurement device of gas of data are provided, comprise sensor (9), drive link (10) and guide head (12), it is characterized in that outer tube (8) is fixed on the jag of center-pole 2A and center-pole 2B, fix the relative position of two center-pole 2A and 2B, constitute whole, inner sleeve (7) is set in the inside of outer tube (8), one end is fixed on the center-pole 2A, the other end can slide on center-pole 2B, drive link (10) one ends are fixed on the center-pole 2B, the other end is fixed on the center-pole 2A with regulating bolt (3), regulating bolt (3) can regulate, and center-pole 2A is connected anchoring body (1) respectively with 2B.
